I need to make some modification to an existing robot, S4 system. See the unit info from EIO.cfg:
EIO:CFG_1.0:3:1::
EIO_UNIT:
-Name “SW_BOARD” -Type “d328” -Bus “BASE” -Digin 16 -Digout 16
-Name “SIM_BOARD” -Type “eip000” -Bus “SIM” -Address “” -Digin 25
-Digout 25
-Name “SWCOM_BOARD” -Type “eip000” -Bus “SIM” -Address “” -Digin 25
-Digout 25
-Name “SW_SWIT1” -Type “reio” -Bus “SIM” -Address “” -Digin 64 -Digout 64
-Name “SW_SWIT2” -Type “reio” -Bus “SIM” -Address “” -Digin 16 -Digout 16
-Name “SW_SWIT3” -Type “reio” -Bus “SIM” -Address “” -Anin 8

“SIM_BOARD” is an virtu I/O board which does not physically exist?
I see some I/O signal were defined under SIM_BOARD. So this signal is only for program use and can not be connected to real ouside equipment?
