It typically is used to control electromechanical equipment in a complex setting plc communication problems such as a manufacturing assembly line or for simple applications, mitsubishi plc error codes such as turning on and off the lights a business uses at night or during allen bradley plc error codes the day. A PLC communication error happens when the PLC doesn't respond to communication requests or responds negatively to such requests. A PLC communication error

can occur between the programmable computer and the devices it controls or when the technician attempts to program the device from afar.Error CodesProgrammable logic controllers are built by a variety of manufacturers and are designed for specific uses. Each company has a series of error codes that refer to its specific controllogix msg error codes PLC. For instance, a timeout error can cause a device to not communicate properly, or a checksum error can be generated when the communication package is the incorrect size. Another communication error can occur when the PLC does not reply to the last message request or does not have enough time to respond to the request.CommunicationsPLCs can communicate via serial ports to other equipment or by hooking up a monitoring device on the RS-232 modem port available on the PLC. A modem connection that isn't seated properly in the port can cause a communication error to occur when trying to access the device using a cellular telephone or other communication device. When connected to a remote monitoring device, a technician can program the PLC from afar, send and receive data and view PLC logs. Interruptions in the signal will also cause communication errors.Defective PartsDefective communication boards within a PLC can al

By SteveYYY on 29 May, 2002 - 10:07 amOne PLC 5/20E was doing MSG instruction to write data to an SLC 5/05. The http://control.com/thread/1026150531 instruction was moved to another PLC5/20E, keeping everything else the same. But the new PLC kept getting error every few hours "privilege error, access denied". Resetting the error bit allowed the MSG to operate again until another error. Any idea why? Thanks.SteveBy Ken Roach on 29 May, 2002 - 5:17 pmUsually that error is seen in programming software when you actually have protected some of the memory of a controller.So, here I go answering your question with more questions:Are you reading or writing to the SLC ? Are you addressing Integer (N7:xx) data files, or the I/O table directly (the ability of PLC-5's to access the SLC I/O table directly has been varied across the years). It would be instructive to know if the "new" PLC-5/20E was newer or older than the original.If you programmatically reset the .ER bit and retry the message... how often does the message fail with the error compared to completing correctly ? Does the mess
