Help me! Communication error 3 NT5Z-ST121B-EC, SYSMAC C200HG

Hello.

I need your help.

I have the following problem:

Touch panel NT5Z-ST121B-EC and PLC SYSMAC C200HG
Connected to each other by a communication cable on the RS-232 port from the PLC and COM1 side from the side of the panel (Documentation did not find, can badly searched, IMHO Chinese branch.)

On the panel alternately 3 or 4 windows with an error, only the memory area changes:
Communication error 3
Com 1 station 0
IR20 error reading
Controller No answer ...
Check the connection, the setting of the communication parameter

The communication cable was checked.
I checked In the port panel settings: parity, speed, stop bits.
On the PLC side, too, checked, the port settings are the same.
The port communication indicator on the PLC blinks.

What could I miss?
Can one of the two ports fail?

The panel has a second port.
Thought to adjust it and check with it, but while "newbie" in OMRON,
Is there anything to configure (configure) on the PLC side?
Tell me, please.

P.S.

With OMRON previously did not work (Koyo, Siemens, ...)
