8.15.1 Interface definition input
The input map definition for signals to PowerMACS is according to the following table:
Word Byte Bit Name in DeviceNet map Name of
IO signal
Pass through
IO signal
0
0
0 Green Light (Pass through to IO) DO_GM_GreenLight
1 Yellow Light (Pass through to
IO) DO_GM_YellowLight
2 Red Light (Pass through to IO) DO_GM_RedLight
3 Alarm Horn (Pass through to IO) DO_GM_AlarmHorn
4-6 Spindle
– Mode Set Code (1-8)
DI_GM_ParSet1 - 4 DO_GM_ParSet1 - 4

0 Start Cycle DI_GM_Start
1 Reverse DI_GM_Reverse
2 Error Proofing Ready (EPR) DI_GM_EprIn DO_GM_EprOut
3 Spindle
– Stop/Disable
DI_GM_StopDisable
4-7 Spare
1 0-1 N/A Spare
2-3 0-3 N/A PVI number
The inputs are used as follows (all signals have positive logic where active is 1 and passive is 0):
Green Light: This signal is just passed through to PowerMACS discrete I/O interface (local I/O).
Yellow Light: This signal is just passed through to PowerMACS discrete I/O interface (local I/O).
Red Light: This signal is just passed through to PowerMACS discrete I/O interface (local I/O).
Alarm Horn: This signal is just passed through to PowerMACS discrete I/O interface (local I/O).
Spindle
– Mode Set Code
: Used to choose the mode that should be run when Start Cycle goes high
(could be 0 to 7 witch will correspond to Mode 1 to 8 in the stations Mode Table). This
signal is sampled continuously as long as no cycle is running and is echoed to the output
signal
Spindle
– Mode Set Code
.
Reverse: When this signal is 1 it will override the value of Mode Set Code and force mode to the
value 9 for a reverse program. This signal is sampled continuously as long as no cycle is
running.
Start Cycle: Starts the tightening cycle if the Error Proofing Ready signal has switch from 0 to 1 since
the last cycle and Spindle - Stop/Disable is low. The cycle is started using the current
value of Spindle
– Mode Set Code
or Reverse . Immediately when starting the cycle all
green, yellow and read indication lamps are turned off (for the DeviceNet and as well as the
I/O interface).
