Hello Experts,

I have a query regarding the connection of 8 panels, each equipped with an ET200SP PLC with IO. These ET200SP PLCs are linked to an S71515 F PLC, which serves as the master, all operating on Profinet. In the machine, I plan to connect only 7 panels to 7 units out of the total 8. My question is how to understand which panel is connected in which unit?

Regards,

Make a drawing ?

You should explain what means for you understanding what is connected to what. E.g. Profinet devices have names, which can be used for this purpose possibly. Or maybe the panels can be connected to the units on demand and connections can change. Then this is completely different issue. We need more details to be able to give any recommendations.

You may want a single S7-1500 level PLC to handle ALL the HMIs - if I am understanding the needs correctly.

Have it be the HMI - PLC gatekeeper so you have a single HMI project loaded onto 7 HMIs.

In each HMI project, there is exactly 1 connection between an HMI tag and a PLC tag.  You _can_ have 7 identical screens with 7 different PLC tags and 7 different HMI tags, or use a faceplate type thing that selects the correct HMI tags depending on what PLC is selected.

It gets very complicated sharing HMIs across PLCs if things are not well architected, designed, built, commissioned, and tested.

Hello,

I have attached the layout. I think my statement confused both of you. I will correct it.

I have a query regarding the connection of 8 units (7units + 1 spare) each equipped with an ET200SP PLC with IO. These ET200SP PLCs are connected to an S71515 F PLC, which serves as the master. Operating on Profinet protocol. 

I have a application, where a machine has 7 units to handle 7 different fluids. The units with ET200SP IM PLC will be connected to these 7 units to handle these fluids. These 7 IM PLC units can be placed anywhere in any units. So, My question is, how my S71515F PLC understands which ET200SP IM PLC unit is connected in which fluid handeling unit? How my S71515F PLC know ET200SP PLC Unit is connected to 6th fluid handeling units lets say? Like wise. 

Regards,

• each fluid handling unit is equipped in coding device (e.g. it can be a socket with specific connection of pins which is read by IOs of ET200SP PLC)
• ET200SP PLC unit recognizes this coding and changes its profinet device name accordingly
• S71515 F PLC checks which units exists on the network and processes them accordingly, optionally not existing units can be disabled
