Communicating between 32 bit Simulink and 64 bit Simulink

I have a mex32 file which I run on a 32 Bit 2014b Simulink simulation but my actual model which uses the mex32 is on 64 bit 2018b Simulink which cannot be ported to 64 bit due to some reasons. Is it possible to have both the 32 Bit and 64 Bit Simulink opened at the same time and some how connected which will allow the simulation to be connected between both the Simulinks and Signals could flow back and forth between both the Simulinks in real time and syncrhonized? I hope the following picture gives a better view:

Finally found the solution to my problem. Using UDP communication instead of TCP does the trick. The following MATLAB example can be used https://www.mathworks.com/help/instrument/basic-udp-communication.html

By splitting the example into 2 parts one with the receiver and one with the sender, and running them on two different simulinks, in my case, 32 and 64 Bit, I was able to connect, sync and run the simulation as originally wanted.

Use TCP to communicate between the processes.

Thankyou for the answer. I tried using TCP/IP blocks as the following picture described.

I have setup the echo Server correctly, have also made sure that both the models and the blocks as have a fixed sample time of 0.01. But I am still getting the following error:

I always run the receive block simulation first as it has a time out so it can wait and then run the send block simulation but no luck so far.

Have you experimented with the example at https://www.mathworks.com/help/instrument/send-and-receive-data-over-a-tcpip-network.html ?

Yes I followed that tutorial and it worked but only on one Simulink Model as the tutorial does the receiving and sending on the same Model. When split up the sending part to another Simulink model, in this case 2014b 32 Bit then I started receiving this error.
