Hello,
I have a linear actuator set up (2 Ewellix linear actuators with hall effect sensor encoders) and an SCU control unit with RS232 communications. The SCU provides a nice command set, and data, such as actual position of actuator1, can be directly accessed. The network layer for this is a Point to point connection. The control unit functions as slave and replies to the requests of the master (e.g. PC program). The slave replies to each request from the master. The manual for the SCU shows example code in C++ to be coded on a connected PC. I want to, at the very least, get the encoder readings from the SCU to calculate the position of the roller attached to the actuators and display this value. My first thought was to use a flat panel PC to run this code with a simple GUI to display the positions and possibly buttons to extend, retract and send the roller to a commanded position. My question is though, could an Allen Bradley ASCII module namely a 1734-232ASC (point I/O very proximate to the SCU of actuators) or a 1769-ASCII be integrated to perform the same tasks? I am new to these modules and possible configurations. Are there instructions to access specific data locations using RSLogix 5000 via the modules listed? Or is the entire data set polled and subsequently parsed in RSLogix.
