I/O lookup

46 inputs, 43 outputs, 59 of them with a working note. Type an address, a wire number, a module terminal, or any word from the description - in English or in the original Italian. Filtering is instant and works offline once the page has loaded.

🔴 Wire numbers are read from the wiring diagram, via io-map.md - not computed from the address. Most follow the E1nn / A2nn pattern, but OF.41-OF.47, the carousel group, are labelled A1-A7 on the diagram. Take what is in this column to the machine; the pattern would have sent you looking for seven wires that do not exist.

⚠️ Two output terminals, OF.31 and OF.39, are wired in the rack but carry no PLC symbol and no wire label, so they have no row here. See io-map.md.

🔴 Ribbon ways are not in address order. Each ribbon carries three modules of eight, and the module blocks sit on it in reverse - the third module on ways 1-8, the second on 9-16, the first on 17-24 - while the eight points inside each block ascend normally. Ways 25 and 26 are joined on the board and are the shared negative. Mapped by Grant on 9 September and verified against all 96 points.

Address	Ribbon way, colour	Wire	Module:term	Symbol	Description English, then the original	Notes
IF.1	CN1 way 17 purple 2	E101	IF1:2	IF_START_ZONA1	Start button, zone 1 (N.O.) START ZONA 1 (A-J) (N.O.)	One green button per zone. Only accepted once the zone's workpiece is clamped and its lamp is lit.
IF.2	CN1 way 18 grey 2	E102	IF1:3	IF_START_ZONA2	Start button, zone 2 (N.O.) START ZONA 2 (C-L) (N.O.)	As zone 1. In pendulum working this can be pressed while the other zone is still cutting - the machine books it and starts the instant the current program ends.
IF.3	CN1 way 19 white 2	E103	IF1:4	IF_BLOCCO_AEI	Clamp pedal, zone 1 (N.O.) PEDALE BLOC. PEZ. CAMPI A/E/I (N.O.)	Two-press cycle, gated by the PLC. Press-and-release once to raise the stops, float the table and free the vacuum; again to set the panel down and clamp it. Dead unless the machine is expecting a load.
IF.4	CN1 way 20 black 2	E104	IF1:5	IF_BLOCCO_DHL	Clamp pedal, zone 2 (N.O.) PEDALE BLOC. PEZ. CAMPI D/H/L (N.O.)	As zone 1.
IF.7	CN1 way 23 orange 3	E107	IF1:8	IF_HOLD	Hold / feed hold (N.C.) HOLD (N.C.)	ANDed with both zone photocells into one chain. During a manual reset a break here raises a full emergency, not a hold.
IF.8	CN1 way 24 yellow 3	E108	IF1:9	IF_EMERG_TERM	Emergency stop chain (N.C.) EMERGENZA (N.C.)	A single series chain, not a per-zone breakdown - every per-zone emergency input in the software is unfitted. Includes the rope switch. Keep it hardwired to the drive enables and the main contactor; Mesa monitors, never arbitrates.
IF.9	CN1 way 9 white 1	E109	IF2:2	IF_CONTR_VUOTO	Vacuum healthy (N.C.) CONTROLLO VUOTO (N.C.)	The machine's only vacuum sensor - the per-field ones are a generic branch and are not fitted. Enforced only while a program is running, so setup and jogging still work with the pump off.
IF.10	CN1 way 10 black 1	E110	IF2:3	IF_AGGR_SU	Aggregates up (N.O.) AGGREGATI SU (N.O.)	Six symbols share this one address as a SERIES CHAIN. It is one input meaning 'everything on the head is retracted', not six separate points. Any one unit down breaks it.
IF.10	CN1 way 10 black 1	E110	IF2:3	IF_MANDR_1_SU	Router 1 off / up (N.O.) PANT 1 OFF. (N.O.)	Part of the IF.10 series chain.
IF.10	CN1 way 10 black 1	E110	IF2:3	IF_MANDR_2_SU	Router 2 off / up (N.O.) PANT. 2 OFF (N.O.)	Part of the IF.10 series chain. Not fitted.
IF.10	CN1 way 10 black 1	E110	IF2:3	IF_MANDR_3_SU	Router 3 off / up (N.O.) PANT. 3 OFF (N.O.)	Part of the IF.10 series chain. Not fitted.
IF.10	CN1 way 10 black 1	E110	IF2:3	IF_MANDR_4_SU	Router 4 off / up (N.O.) PANT. 4 OFF (N.O.)	Part of the IF.10 series chain. Not fitted.
IF.10	CN1 way 10 black 1	E110	IF2:3	IF_MANDR_5_SU	Router 5 off / up (N.O.) PANT. 5 OFF (N.O.)	Part of the IF.10 series chain. Not fitted.
IF.11	CN1 way 11 brown 2	E111	IF2:4	IF_LAMA_NON_AGGR_SU	Saw unit retracted (N.O.) GRUPPO LAMA TESTA OFF (N.O.)	Pneumatic. Reads faulted with the air off - expected, not a problem.
IF.12	CN1 way 12 red 2	E112	IF2:5	IF_OVERR0	Feed override, bit 1 (N.O.) BIT 1 OVERRIDE (N.O.)	Four bits, IF.12-IF.15, from a rotary selector.
IF.13	CN1 way 13 orange 2	E113	IF2:6	IF_OVERR1	Feed override, bit 2 (N.O.) BIT 2 OVERRIDE (N.O.)
IF.14	CN1 way 14 yellow 2	E114	IF2:7	IF_OVERR2	Feed override, bit 3 (N.O.) BIT 3 OVERRIDE (N.O.)
IF.15	CN1 way 15 green 2	E115	IF2:8	IF_OVERR3	Feed override, bit 4 (N.O.) BIT 4 OVERRIDE (N.O.)
IF.16	CN1 way 16 blue 2	E116	IF2:9	IF_MOT_PANT_RES	Spindle contactor engaged (N.O.) TELERUTT. INSER. INV. 1 (N.O.)	Confirms the inverter's line contactor actually pulled in.
IF.17	CN1 way 1 brown 1	E117	IF3:2	IF_PREUTE1	Tool present in spindle (N.O.) PRESENZA UTENSILE C.U. 1 (N.O.)	Checked at every step of the tool change. A tool that will not seat gets five attempts before the cycle faults.
IF.18	CN1 way 2 red 1	E118	IF3:3	IF_SBLOCCO_UTE1	Manual tool-release button (N.O.) SBLOCCO MANUALE C.U. 1 (N.O.)	The operator's own button on the head, separate from the ATC.
IF.20	CN1 way 4 yellow 1	E120	IF3:5	IF_PIST_CAMBIO_SU1	Tool-change piston up (N.O.) PISTONE C.U. 1 SU (N.O.)
IF.21	CN1 way 5 green 1	E121	IF3:6	IF_PIST_CAMBIO_GIU1	Tool-change piston down (N.O.) PISTONE C.U. 1 GIU (N.O.)	The name is misleading. Physically this is the spindle zero / index position sensor, drawn as -SQ203 on sheet 18.
IF.22	CN1 way 6 blue 1	E122	IF3:7	IF_FC_ASSEU	X axis overtravel (N.O.) EXTRACORSA ASSE U (N.O.)	The hard overtravel limit, and it does reach the controller through the ribbon - LinuxCNC will see it. Separate from the HOME switch, which goes back to the axis card on pin 6 and appears nowhere in the software.
IF.23	CN1 way 7 purple 1	E123	IF3:8	IF_FC_ASSEV	Y axis overtravel (N.O.) EXTRACORSA ASSE V (N.O.)	As X.
IF.24	CN1 way 8 grey 1	E124	IF3:9	IF_FC_ASSEW	Z axis overtravel (N.O.) EXTRACORSA ASSE W (N.O.)	As X.
IF.25	CN4 way 17 purple 2	E125	IF4:2	IF_VEL_RAGG	Spindle at speed (N.O.) INVERTER 1 ON (N.O.)	Do NOT pin this true to make a config run. Fault 1003 exists specifically to catch the spindle dropping out of speed DURING a cut, and a pinned input disables it.
IF.26	CN4 way 18 grey 2	E126	IF4:3	IF_GRUPPO_ORIZZ1	Horizontal borer 1 retracted (N.O.) FORATORE ORIZ. 1 OFF (N.O.)	Pneumatic. Reads faulted with the air off - expected.
IF.27	CN4 way 19 white 2	E127	IF4:4	IF_GRUPPO_ORIZZ2	Horizontal borer 2 retracted (N.O.) FORATORE ORIZ. 2 OFF (N.O.)	Pneumatic. As borer 1.
IF.28	CN4 way 20 black 2	E128	IF4:5	IF_GRUPPO_ORIZZ3	Horizontal borer 3 retracted (N.O.) FORATORE ORIZ. 3 OFF (N.O.)	Pneumatic. As borer 1.
IF.29	CN4 way 21 brown 3	E129	IF4:6	IF_END_CYCLE	End-cycle button (N.C.) END-CYCLE (N.C.)	Normally closed, so a broken wire or a stuck button looks like a permanent end-cycle request. Worth checking early when the machine will not start and the E-stop chain looks healthy.
IF.30	CN4 way 22 red 3	E130	IF4:7	IF_JOGM	Jog minus (N.O.) INGRESSO JOG - (N.O.)
IF.31	CN4 way 23 orange 3	E131	IF4:8	IF_JOGR	Jog rapid (N.O.) INGRESSO JOG RAPIDO (N.O.)	Held with jog + or - for rapid rate.
IF.32	CN4 way 24 yellow 3	E132	IF4:9	IF_JOGP	Jog plus (N.O.) INGRESSO JOG + (N.O.)
IF.33	CN4 way 9 white 1	E133	IF5:2	IF_FOTOC_Z1	Photocell, zone 1 (N.C.) FOTOCELLULA ZONA 1 (N.C.)	Armed and disarmed per zone. Disarming pins its term of the hold chain high - which is the whole point, because the operator loading this zone stands in its beam for the entire load.
IF.34	CN4 way 10 black 1	E134	IF5:3	IF_FOTOC_Z2	Photocell, zone 2 (N.C.) FOTOCELLULA ZONA 2 (N.C.)	As zone 1.
IF.35	CN4 way 11 brown 2	E135	IF5:4	IF_POS_RAGG_CU_6	Carousel in position (N.O.) POSIZ. RAGGIUNTA C.U. 6 (N.O.)	The indexer's COIN output. Verify the five echo bits against what was commanded before trusting it - a carousel can report 'arrived' at the wrong pocket.
IF.36	CN4 way 12 red 2	E136	IF5:5	IF_BIT1_GIOSTRA_CU_6	Carousel position echo, bit 1 (N.O.) POSIZ. GIOSTRA C.U. 6 BIT 1 (N.O.)	Five bits, IF.36-IF.40.

IF.46	CN4 way 6 blue 1	E146	IF6:7	IF_RES_GIOSTRA_CU_6	Carousel homed at pocket 1 (N.O.) RESET GIOSTRA IN POS. 1 C.U. 6 (N.O.)	From proximity switch -SQ560 via relay -KA560. The indexer homes itself; this only tells the controller it happened.
OF.1	CN10 way 17 purple 2	A201 (also wire 17)	UF1:2	OF_CNC_OK	Controller healthy (watchdog) CNC OK	Must be pulsed or held by whatever replaces the Tecnos, or the machine will not enable. Do not leave it hardwired true.
OF.2	CN10 way 18 grey 2	A202	UF1:5	OF_SBLOCCO_CAMPO_AEI	Workpiece RELEASE, zone 1 SBLOCCO CAMPI A/E/I	Energised = released, de-energised = HELD. Inverted from the name and deliberately fail-safe: lose 24 V and the panel stays clamped. Keep that sense.
OF.3	CN10 way 19 white 2	A203	UF1:8	OF_SBLOCCO_CAMPO_DHL	Workpiece RELEASE, zone 2 SBLOCCO CAMPI D/H/L	As zone 1. Same inverted, fail-safe sense.
OF.6	CN10 way 22 red 3	A206	UF1:17	OF_RIF_Y_CAMPO_A	Y datum stop, zone 1 RIF. Y CAMPO A	One solenoid shared with field E - the software names two fields, the hardware has one valve.
OF.6	CN10 way 22 red 3	A206	UF1:17	OF_RIF_Y_CAMPO_E	Y datum stop, field E RIF. Y CAMPO E	The same physical solenoid as field A.
OF.7	CN10 way 23 orange 3	A207	UF1:20	OF_RIF_Y_CAMPO_D	Y datum stop, zone 2 RIF. Y CAMPO D	One solenoid shared with field H.
OF.7	CN10 way 23 orange 3	A207	UF1:20	OF_RIF_Y_CAMPO_H	Y datum stop, field H RIF. Y CAMPO H	The same physical solenoid as field D.
OF.8	CN10 way 24 yellow 3	A208	UF1:23	OF_LAMPADA_AEI	Zone 1 lamp LAMP. CAMPO A/E/I	The lamp IS the operator interface. Steady = clamped and ready to start. Flashing = this zone is yours to load. Dark = keep out.
OF.9	CN10 way 9 white 1	A209	UF2:2	OF_MOT_PUNTE_VERT	Drill block motor MOT. PUNTE VERTICALI	Gates all ten vertical drills. A drill dropped onto the work with its motor stopped will jam or snap.
OF.10	CN10 way 10 black 1	A210	UF2:5	OF_PUNTA_VERT1	Vertical drill 1 down PUNTA VERT. 1 ON	Ten vertical drills: OF.10-OF.15 and OF.25-OF.28.

OF.19	CN10 way 3 orange 1	A219	UF3:8	OF_CONTRO_PRESS	Counter-pressure CONTROPRESSIONE	Presses down on the panel opposite a boring or sawing unit. Not the same thing as the unfitted 'double pressure' option.

OF.23	CN10 way 7 purple 1	A223	UF3:20	OF_PANT1_SU	Router ram RETRACT PANT. 1 OFF	Double-acting pair with OF.24 - never energise both. The retract is deliberately NOT gated on the cut permit: you must always be able to pull the cutter out.
OF.24	CN10 way 8 grey 1	A224	UF3:23	OF_PANT1_GIU	Router ram PLUNGE PANT. 1 ON	This is the cut. The machine is 2.5D - Z positions the carriage, this ram plunges to a hard stop, and the cut happens in XY with Z stationary. Gated on the full cut permit.

OF.30	CN13 way 22 red 3	A230	UF4:17	OF_RIF_X_CAMPO_DHL	X datum stop, zone 2 RIF. X CAMPI D/H/L	As zone 1.

How to read the two descriptions

The English line is a plain-language reading of what the point does, written from the wiring diagram and the PLC rather than translated word for word. The italic line under it is the original from MW310.EQU, kept verbatim so any row can be traced back to the machine's own file - and so the filter still finds giostra, battuta or pantografo.

Where a name is actively misleading - BIT1 that is really a strobe, SBLOCCO that is energised to release - the Notes column says so. Those are the rows that cost you a day if you take the name at face value.

Two things this table cannot tell you

Six addresses carry more than one symbol. IF.10 alone carries six - it is a series chain, not six separate points. The machine has 41 real inputs and 41 real outputs, not 46 and 43.

The ATC output symbol names do not match the hardware. What MW310.EQU calls BIT1 is physically the strobe, and every carousel position bit shifts by one. Build the ATC from the wiring diagram, never from these names.

The derivation of module and terminal from the address, and every point's cabinet terminal, Harting pin and field device, are in the full I/O map.
