7.3 Assignment of Communication Channels
7.3.1 Assignment of communication channels
When the communication expansion board or special communication adapter is used, the main unit (CPU)
automatically assigns communication channels at the time of power ON. The number of available
communication channels varies depending on the main unit type.
• Main unit (40/60 point type) : Max 2ch
• Main unit (14/24 point type) : Max 1ch
1. In the case of main unit (40/60 point type)
"Ch1" is assigned to the communication expansion board connected to the BD1 connector or the first special
communication adapter connected to the connector conversion adapter.
"Ch2" is assigned to the communication expansion board (FX
3G-8AV-BD included) connected to the BD2
connector or the second special communication adapter connected to the connector conversion adapter.
2. In the case of main unit (14/24 point type)
"Ch1" is assigned to the communication expansion board (FX3G-8AV-BD included) connected to the BD
connector or the special communication adapter connected to the connector conversion adapter.
ch1
Only between the communication expansion board (FX3G-8AV-BD included)
and the special communication adapter (which requires the connector
conversion adapter) can be used.
