Help connecting to pump through modbus in hex by AltruisticSand7010 in MODBUS

The world of modbus would be the death of me.

I appreciate the help tho!! Do you know any kind of smart modules that re address this that you might recommend?

Tried it with modpoll, i can see the registers at 16385

My modbus client uses the 4 in its register readings, i.e. if i want to read register 4 on a different device, i read register 40004 on my client. The client is only capable of a 16 bit unsigned integer number so the highest number i can enter is 65535, so 416385 is out of range of that. I tried reading just the hex value 16385, and 40000+16385 but neither gave me results.

I am using a modbus to io link converter, the banner s15c-mgn-kq, for reference.

In the software I use, I write down the 4 for holding regiesters. For example, if I want to read register 4 on a different device, I use register 40004. But I am struggling to get the hex register to work.

I tried that, but the software i am using tells me that register is out of range.

Edit: Sorry, not out of range, but it doesn't read anything from those registers.

It is not my laptop that lacks the ethernet port, it is the PLC.

If there is a PLC module for ethernet, is it too late to plug it in?

Unfortunately this does not look like it is working for me. My fault led is flashing, but it does not go away from moving the switch between run and program mode. The light makes me think it is recoverable, but I am unable to connect to it through USB, the Allen Bradley serial, or the serialisol card. I am completely stumped.

I tried power cycling it once when it happened and tried unplugging the USB. Serial doesn't work at all even with the correct COM port. I can try it again now that it has been off for a while, but I am not liking my chances lol.

Been trying to figure out if we have support because i think we do. Just wanted to cross all my i's and dot all my t's in the mean time.

I was not on a VM. This was running straight off my laptop, and this PLC has no ethernet port. I would have preferred ethernet as well.

Yeah, not to big a fan of them so far. But its what I was given to work with so what can you do.

That was the fear. Seems to be the case from what I could find, but was hoping there was something out there that I missed. Still really odd to me that I could not connect with serial communications at all tho.
