Customers want the PLC to be as small as possible. Possible reasons:

1. Space limitation: Industrial use sites may face limited installation space. Small-sized PLCs are easier to install in limited spaces and are more convenient to use.

2. Cost savings: Small size PLC usually means lower manufacturing costs and material costs. Customers may wish to reduce the capital investment required to purchase and maintain a PLC.

3. Flexibility: Small PLCs may be easier to integrate into existing systems to meet specific needs. Customers may want to use smaller PLCs to implement flexible control and automation solutions.

4. Simplified installation and maintenance: Small-sized PLCs may be easier to install and maintain. Customers may wish to reduce complexity and effort during installation and maintenance.
