Monitoring and/or control device for e.g. programmable logic controller, has voltage supply module that feeds supply voltage for connected system modules if one system module is removed from sequence of system modules

摘要

A bridge module (B) is provided at the end of the assembly of system modules (S 1-S n) opposite a field bus coupling module (S 1) and/or opposite a voltage supply module (S 2). The field bus coupling module connects a system bus (4) to a field bus (7). The voltage supply module feeds a supply voltage for the connected system modules if one system module is removed from the sequence of system modules. An independent claim is also included for a bridge module.
