5.3 Meaning of the contents of the different protocol modes
PLC-Out:
The data refers to the PLC output of the DIGIFORCE
®
. The data described
here is the data transferred from the DIGIFORCE
®
type 9310 to the master.
The function of the PLC-In / PLC-Out bits is identical to the parallel PLC I/O
ports on the unit itself and can be found from the operating manual for the
unit.
5.3.1 PLC outputs Byte 1 (PLC signal lines OK/NOK, Ready etc.)
PLC outputs Byte 1 (Slave Æ Master)
Valid values: S2 Bit 0 LSB
S1 Bit 1
Spare bits to are set to '0'
NOK online Bit 2
NOK Bit 3
OK Bit 4
READY Bit 5
spare Bit 6
spare Bit 7 MSB
5.3.2 PLC outputs Byte 2 (program addressing, switching points)
PLC outputs Byte 2 (Slave Æ Master)
Valid values: STROBE Bit 0 LSB
Prog0 Bit 1
Spare bits to are set to '0'
Prog1 Bit 2
Prog2 Bit 3
OK-STEST Bit 4
Test running Bit 5
spare Bit 6
spare Bit 7 MSB
5.3.3 PLC outputs Byte 3 (device status)
PLC outputs Byte 3 (Slave Æ Master)
Valid values: Status 2

Bit 5
general error Bit 6
internal comms error Bit 7 MSB
Bit 0 device is in the profibus-menu (no communication)
Bits 1-5 give the current device status, where not all options are used yet.
Bit 6 provides the internal watchdog status between the communications card
and the measurement processor.
Bit 7 identifies a general internal communication error (Block transfer)
