EIO24088 Bus Expansion Card Manual Version 1.1

2.1.7 IO Start Number Configuration
Local IO of EIO24088 is mapped into master controller through NODE_IO
Grammar: NODE_IO (slot, node) = iostart
slot
the bus slot number of controller, default is 0
node
Device number, start from 0, 0-
iostart
IO start number to be set, input and output start numbers
of single equipment are the same.
Note:
IO start number of NODE_IO instruction only can be set to multiples of 8,
like, 0, 8, 16, 32, etc. If iostart inputs 30, means it should be set as 24. If expanded
IO number and controller itself IO repeat, they become invalid simultaneously, so
it is not recommended. Firstly, check the controller status to know the local IO
maximum value of controller exactly, then use NODE_IO instruction.
Local input 24-31 can configure as drive ALM signal, but it is recommended to
configure as alarm signal through master controller ALM_IN instruction.
Local output 8-15 can configure as drive automatic enable signal, or enable through
master controller OP instruction directly. After it is configured automatic enable,
master controller can’t control relative output port directly.
