11.22.2 SX-bus Communication Card (OPC-SX)
The SX-bus communication card is used to connect the FRENIC-MEGA and Fuji programmable controller MICREX-
SX series by SX-bus. Automatic operation and monitoring can be performed, and function code settings necessary
for operation can be changed or checked with MICREX-SX programs.
Applicable port
This communication card can only be installed in the A port of the three FRENIC-MEGA option card connection
ports (A, B, and C ports).
[Note] This communication card uses certain B port functions, and therefore only a relay output card can be installed
in the B port.
[Note] When this communication card is installed, it cannot be used in combination with other communication cards
(DeviceNet communication card, PROFIBUS DP card, etc.) If these communication cards are mistakenly installed
at the same time, communication error alarm er4 will occur.
