[2] Address allocation of I/O relay
This section describes I/O relay addresses allocated to the Z-336J.
(1) When mounted on Z-311J/312J
The total number of Z-336J boards able to be mounted including other communication boards is two
at maximum. Below the switch settings of the Z-336J and allocation of I/O relay are shown.
When using one communication board (Z-336J)
Set switch SWA for number of communication boards on the Z-336J as follows.
When using two communication boards
Depending on at which position the Z-336J is used, the allocation of I/O relay varies.
Examples of allocation
Below the switch setting and I/O allocation when using two Z-336J is shown.
R = 0, S = 0
R = 0, S = 1
R = 0, S = 2
R = 0, S = 3
