anyhow it does not make sense to create a plugin, where you can select up to 4 of those IO Card's and then
you do not have Access to all I/O's. i am pretty sure that all the I/O's are reflected to somewhere. in the CSMIO,
witch i am using you can Access all the I/O's via the modbus functions GetInBit(adr,bit) and SetOutBit(adr,bit) and
ResetOutBit(adr, bit), but without more Information it is hard to find the right adress.
maybe you have a Chance to contact Steve Murphree via NFS Support?
