Operating Instructions COMPAX-M / -SDigital inputs and outputs1388.6 InterfacesThe COMPAX interfaces for data and status are digital inputs with an PLC datainterface, an RS232 interface and an optional bus interface (interbus S, CAN bus,CANopen, profibus, CS31 or RS485).The RS232 interface can be operated simultaneously with other interfaces.8.6.1 Digital inputs and outputsTo control the program process, 16 inputs and 16 outputs are available (8 inputsand 8 outputs with COMPAX 1000SL).O7-O11 and I7-I11 are assigned when the PLC data interface is switchedon.Input AssignmentI1 (X8/1; X19/x) SHIFTI2 (X8/2; X19/x) Manual+I3 (X8/3; X19/x) HandñI4 (X8/4; X19/x) QuitI5 (X8/5; X19/x) STARTI6 (X8/6; X19/x) Stop (interrupts data record)I7 (X8/7; X19/x) Freely assignable in the standard unit.I8 (X8/8; X19/x) Freely assignable in the standard unit.SHIFT I2 Find machine zero (MZ)SHIFT I3 Approach real zero (RZ)SHIFT I4 Teach real zeroSHIFT I5 reservedSHIFT I6 Break (breaks off data record)I9 (X10/1; X19/x) Freely assignable in the standard unit.I10 (X10/2; X19/x) Freely assignable in the standard unit.I11 (X10/3; X19/x) Assigned when P232=4 (activates position adjustment);otherwise free.I12 (X10/4; X19/x) Freely assignable in the standard unit.I13 (X10/5; X19/x) Freely assignable in the standard unit.I14 (X10/6; X19/x) Assigned when mark reference is activated (P35=1)(activates mark reference); otherwise free.I15 (X10/7; X19/x) Fast start (can be activated using P18)I16 (X10/8; X19/x) Is assigned if mark reference is activated (P35=1) (markinput); otherwise free.The assignment of inputs on X19 applies only to COMPAX 1000SL.I/O - assignmentof standard unit
