Question

Using the PLC comparison table compare PLC’s from 2 different manufactures in term of support for IEC- 61131, communication protocols and redundancy. Try to explain what the advantage and disadvantage of the support would mean to you as an end consumer

Answer 1

On one hand, an advantage of PLCs is that they are more cost-effective. This means that soft PLCs help in decreasing production costs. On the other hand, the disadvantage is lack of greater security. It should be noted that lack of security reduces reliability on the side of the consumers.
