|EH-150's CPU has two communication ports
: Port 1 and Port 2.
Port 1 can be used as a dedicated port and can be switched to
a general-purpose port. It also supports the modem control function
(except for EH-CPU104A).
Port 2 can be used as a dedicated port for programming devices.
When a general-purpose port is designated, the TRNS command can
be used, making operation easier and improving connectivity.
The interface can be selected from RS-232C, RS-422, and RS-485
for port 1 general-purpose port and the port1 dedicated port (EH-CPU316A,
When Port 1 is used as a dedicated port
Multi-link connection of display
(EH-CPU316, EH-CPU516, EH-CPU548) Port 1 can be switched among RS-232C,
RS-422, and RS-485. Task code communication with a station number by HI-PROTOCOL
can be supported using RS-422.

and comparing programs can be done without a programming device.
The CPU can be operated with the program on the memory board.
A memory board that can store data (384k words) in addition to
the program is also available (EH-MEMD). The memory board employs
a battery-less Flash memory to make maintenance easier.
