How can we have diagnostic information for TMC2xxx additional cartridge analog I/O module within a TM221Cxxx PLC SoMachine/Machine Expert - Basic application program ?
Within TM221Cxxx PLC and SoMachine/Machine Expert - Basic, we have the possibility to add 1 or 2 optional cartridges (depending on the TM221Cxxx PLC reference). Such cartridge provides 2 analog inputs or outputs channels as extension for the M221 PLC local I/Os.
For each channel, it exists a dedicated system word object available for diagnostic .
It’s %IWS.0.i for an analog input channel
It’s %QWS.0.i for an analog output channel
With i defined by this way:
i=100 for the 1st channel of the cartridge located 1st slot
i=101 for the 2nd channel of the cartridge located 1st slot
i=200 for the 1st channel of the cartridge located 2nd slot
i=201 for the 2nd channel of the cartridge located 2nd slot
The definition of the code status/diagnostic value is as below:
