3.3 Performance Specification
*1. An FX2NC-CNV-IF or FX3UC-1PS-5V is necessary to connect the 20SSC-H with the FX3UC PLC.
*2. The MR-J3W- B can be connected within the functional range of the MR-J3- B.
*3. The MR-J3- BS can be connected to the 20SSC-H later than Ver.1.40.
However, it does not support the fully closed loop system.
