Electronic Keying Mismatch in RSLogix
There are few major reasons why you would get electronic keying mismatch error in RSLogix.
Major / Minor Revisions
If the major or minor revisions of the module in the chassis does not match the one set in the program you will get the keying mismatch error.
Catalog Number of the module
If the catalog number of the module [...]
RSLogix 5000 Programming Languages
RSLogix supports different programming languages. Using the right language for the right job can increase productivity, reduce complexity and maintenance costs. These languages are:
Ladder Diagram (LD)
Ladder logic was created such that most engineers and technicians would easily understand it and be able to maintain it. This was achieved by making the language similar to relay circuits [...]
Seal-In Circuit Vs. Latch / Unlatch Sequence in PLC
Latch circuits and Seal-in circuits are types of electronics circuit that have two possible output states. The output is either true or false. They are mostly used as memory to store one bit of information.
In PLCs this can be done by Latch / Unlatch configuration or by a Seal-In sequence. They both have their advantages [...]
