Multiple Connect Request from Same MBTCP Master
Can same master/Client establish multiple Modbus TCP connections to same slave/server???

Currently we have Modbus TCP server which is getting restarted when there are Continuous Connect and disconnect from same master.

To restrict this we did a change such that If there is any available connections from master already then new connection will not be accpeted till old connection is deleted .

But this will restrict allowing Multiple connects from same master. Hence Is this valid use case? DO we need to support multiple connections between same master and same slave?

Have someone came across such scenarios where single master establishing multiple connect with same slave? Does any company products (MBTCP SERVER) allow this?
