)
In AC500 the following interface identifier applies:
14 = I/O bus, 11 = COM1 (e.g. CS31 bus), 12 = COM2.
The PNIO diagnosis block does not contain this identifier.
2
)
With "Device" the following allocation applies:
31 = Module itself,
1...10 = decentralized communication interface module 1...10,
ADR = hardware address (e. g. of the DC551-CS31)
3
)
With "Module" the following allocation applies depending on the master:
Module error: I/O bus or PNIO: 31 = Module itself; COM1/COM2: 1...10 = expansion
1...10
Channel error: I/O bus or PNIO = Module type (2 = DO); COM1/COM2: 1...10 =
expansion 1...10
4
)
In case of module errors, with channel "31 = module itself" is output.
State LEDs
LED State Color LED = OFF LED = ON
Inputs I0...I7 Digital input Yellow Input is OFF Input is ON
Outputs
NO0...NO7
Digital output Yellow Output is
OFF
Output is ON
In the undefined signal range, the state LED for the inputs can be ON although
the input state detected by the module is OFF.
