C40P C40P-EDR-A | OMRON PROGRAMMABLE CONTROLLER

C40PEDRAC40P-EDR-A – 40PT I/O MODULE.The C20P, C28P, C40P, and C60P Expansion I/O Units all have CPU left/right selector switches. The C16P and C4K do not. For those models whichhave the switch, care must be taken to set it so that it corresponds with thedirection of the I/O Connecting Cable. If the switch is set in the wrong direction, the System will operate as if the I/O Unit were not there. Set the switch so that the CPU connector side (Left or Right) is “in,” as shown in the following diagram. Do not change the switch setting after power has been turned ON, as this will cause the I/O bus to malfunction.The tables on the following pages show the possible configurations for a P-type PC. Although the tables branch to show the various possibilities at any one point, there can be no branching in the actual PC connections. You can choose either branch at any point and go as far as required, i.e., you can break off at any point to create a smaller PC System.When implementing a system there is a physical restriction on the total cable length allowable. The sum of the lengths of all cables in the system must be limited to less than 1.2 meters
