I have exsisting system which we are upgrading the two HMI's from Omron NT's to new NS's. Thease will continue to comunicate via RS232 to the OMRON PLC using NT LINK(1:N).
We also have to somehow interface this system to a purewater dosing system to request a number of litres of water and a batch request command. The pure water system then needs to send the quantity batched back and a complete bit. + a handful of other status bit.

The new HMI's we are using have a Ethenet port. Is it possible to use the ethenet port on the HMI to communicate to another PLC to read write some data.
The problem is it not a OMRON PLC is a Siemens S7-300.

So my question is it possible to configure one of my OMRON HMI's to read write a block of data to a S7-300 PLC over ethernet.

PLC & HMI part numbers are below.

PLC OMRON - c200HX-CPU 64E
HMI OMRON - NS10-TV01-BV2 Omron NS10 10.4" TFT COLOUR Ethernet

Need to interface some how to this system. Need to send and receive one setpont and say a word of control and status bits.

S7-315 2PN/DP - 6ES7 315-2EH13-0AB0
 
Ethernet - I do not think so. In list of available hosts (drivers), there are no Siemens PLCs (screenshot 03.jpg).

But, in Serial port 2 (B), which is RS485, there is (screenshot 04.jpg). So I believe that is possible to connect NS10 to MPI port on S7-300. You can define partner (S7-300) MPI address, rack, slot etc., network baudate (max 115,2Kbit/s- you must use 19,2 common for NS and S7-300!!!!!!!).


Please try then inform us here if you had any success.
It's easy job, make you own cable (do not forget to terminate at end nodes).
