The interface module identifier is on the front panel and can therefore be identified when it is installed.
  • Page 198 IF 964-DP interface module 11.1 Using the IF 964-DP interface module The system can be expanded up to 125 stations. Figure 11-1 IF 964-DP interface module Note The IF 964-DP may only be removed or inserted when the power is turned off. If you remove the interface module when the power is turned on, the CPU changes to the DEFECT mode.
