Will begin programming within the Emergency_Stops routine for the safety circuit. One will be named Emergency_Stops and the other VFD_Safety. Below is an AutoCAD wiring diagram where we can see channels 10 and 11 test output channels T0 and T1 on diagram 1.3ĭiagram 1.7b-Revised output configuration of the 1734-OB8S module Programming a Safety Routine in RSLogix/Studio 5000Īfter the modules are configured, we can add two routines underneath the default Safety Program within our Studio5000 program. For example, we can make sure that the input going back to the PointIO module is always on one side of the emergency stop contacts and the corresponding test point on the other. However, it is good practice to set a standard and follow it. The emergency stop contacts are only passing a voltage through, so which side the wires are landed on does not matter. The other side will have a wire coming back to the 1734-IB8S module and landing on input 00, channel 0. Channel A will be wired so that test point 00, channel 6 (highlighted on diagram 1.2) will be wired to one side of the emergency stop’s channel A contact.
Input 00 will be estop channel A and input 01 channel B. This means that for wiring and programming it, we will need two channels – channel A and channel B. The emergency stop is dual channel, normally closed. In this tutorial, we will learn how to wire an emergency stop (estop) button to the 1734-IB8S module.
