• When the "input error output" parameter is set to ON, alarm output 1 turns
ON when an input error occurs.
• Optimum PID constants can be set easily by performing AT (auto-tuning)
or ST (self-tuning).
• With the E5@N-@@@B, the following functions can be executed using
event inputs: switching set points (multi-SP, 4 pts. max.), switching RUN/
STOP status, switching between automatic and manual operation, and
starting/resetting program.
• With the E5@N-@@H@ and E5@N-@@HH@, the heater burnout detection
function and the HS alarm function can be used.
• Communications functions utilizing CompoWay/F (See note 1.), SYSWAY
(See note 2.), or Modbus (See note 3.) can be used.
E5@N-@@@03: RS-485 interface
E5@N-@@@01: RS-232C interface (See note 4.)
(1) CompoWay/F is an integrated general-purpose serial communications
protocol developed by OMRON. It uses commands compliant with the
well-established FINS, together with a consistent frame format on
OMRON Programmable Controllers to facilitate communications be-
tween personal computers and components.
(2) SYSWAY communications do not support alarm 3 output.
(3) Modbus is a communications control method conforming to the RTU
Mode of Modicon Inc.'s Modbus Protocol.
(4) The E5CN and E5CN-U do not support the RS-232C interface.
The E5@N-@@P can be used as the power supply for ES1B Infrared Temper-
ature Sensors.
The external power supply for the ES1B cannot be used on the E5CN-C@@
(Current Output Model).
