8.15.1 Interface definition input
The input map definition for signals to PowerMACS is according to the following table:
Green Light (Pass through to IO)
Yellow Light (Pass through to
IO)
Red Light (Pass through to IO)
Alarm Horn (Pass through to IO)
Spindle – Mode Set Code (1-8)
Error Proofing Ready (EPR)
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).
