Mitsubishi alpha vs Allen Bradley micrologix

To add to the fun 984’s and TSX/Magelis use reversed bit patterns. Bit 0 on TSX is bit 16 on 984’s, even the bit numbering was different. TSX 0→15, 984 16→1, they’re both Modicon!

Was it Modicon that had a BROT (bit rotate) function block in the software?.

Yes BROT, it made life easier with the ModBus connections.
The DX functions made the 984 a versatile piece of kit. EMATH blocks made my brain hurt.
The beauty of Modsoft was being able to put quite comprehensive descriptors to registers. If you had implied registers for a function then the descriptor would point you to the right place. Took time to do, but was worth it in time saved later.

Reliability will be be about the same have a look at the current rating for any relay outputs and ensure this covers your requirements. As mentioned have a look at software costs, programming cables and support. It might be worth looking outside the box and saving yourself some money with a Jazz unit from Unitronics, software is free and it uses a USB programming cable, similar to that found on many smart phones or cameras.

Aren't you those guys who sell the PLCs with HMI integrated? I think I still have the catalogue somewhere. Could you mail me a price list, please? :waving: I lost the contact details!

Thought something seemed familiar.
