5.3.5 GM DeviceNet variables
The following shared memory variables serve as the discrete interface to the GM DeviceNet device. For a
more detailed description of the GM DeviceNet device see chapter: GM DeviceNet.
Even though the following variables are defined as shared memory type, which mean that the PLC
application can read and write to them, they should be used as outputs only (seen from the PLC):

GM_IN
GM_INPUT_TYPE
This variable represents the discrete inputs to the GM DeviceNet device.
GM_INPUT_TYPE is a structure containing the following BOOL flags:
 PARSET1 Parameter set code (1-8) mapped to Mode bit 0 (value 1).
 PARSET2 Parameter set code (1-8) mapped to Mode bit 1 (value 2).
 PARSET3 Parameter set code (1-8) mapped to Mode bit 2 (value 4).
 REVERSE Reverse tool cycle. Uses mode 9 for the reverse
program.
 START A transition from FALSE to TRUE starts a tightening cycle.
Positive edges while a cycle is running or when STOPDISABLE is
True are ignored..
 EPRIN TRUE indicates that a new cycle may be started. PARSETx
are sampled on a positive edge of this signal.
 STOPDISABLE TRUE stops the current cycle and inactivate the
spindles from any future cycle. Must be low to permit a new cycle to
start.
 DISABLEDNETINP When TRUE all inputs via DeviceNet except for
the PVI number are disabled.
Note! This input is always read, regardless of the value of the device
parameter Through discrete I/O (see chapter: GM DeviceNet).
