Communications Setting Level
Set the E5GN communications specifications in the communications setting level. For setting communications parameters, use the E5GN panel.
The communications parameters and their settings are listed in the following table.
Note: The highlighted values indicate default settings.
Before executing communications with the E5GN, set the communi-
cations unit No., baud rate, etc., through key operations as described
below. As for other operations, refer to relevant Operation Manual.
1. Press the
key for at least three seconds in the “operation
level.” The level moves to the “initial setting level.”
2. Press the
key for less than one second. The “initial setting
level” moves to the “communications setting level.”
3. Pressing the
key advances the parameters as shown in the
following figure.
4. Press the
or
keys to change the parameter setups.
Note: On the E5GN, the
Key is the
Key.
Set each communications parameter to match those of the communi-
cating personal computer.
Communications Unit No. (
u-no
)
When communicating with the host computer, the unit number must
be set in each Temperature Controller so that the host computer can
identify each Temperature Controller. The number can be set in a
range from 0 to 99 in increments of 1. The default setting is 1. When
using more than one Unit, be careful not to use the same number
twice. Duplicate settings will cause malfunction. This value becomes
valid when the power is turned OFF and ON again.
Baud Rate (
bps
)
Use this parameter to set the speed of communications with the host
computer. It can be set to one of the following values; 1.2 (1200 bps),
2.4 (2400 bps), 4.8 (4800 bps), 9.6 (9600 bps), and 19.2
(19200 bps).
This setting becomes valid when the power is turned OFF and ON
again.
Data Bits (
len
)
Use this parameter to change the communications data bit length to
7 bits or 8 bits.
Stop Bits (
sbit
)
Use this parameter to change the communications stop bit to 1 or 2.
Communications Parity (
prty
)
Use this parameter to set the communications parity to None, Even,
or Odd.
Troubleshooting
When an error occurs, an error code will be displayed on the No. 1 display. Check the contents of an error and take appropriate countermeasures.
Note 1. If the input is within the range for which control is possible but outside the displayable range (
−
1999 (
−
199.9) to 9999 (999.9)),
will
be displayed if the value is less than
−
1999 (
−
199.9), and
will be displayed if it is greater than 9999 (999.9). Control output and alarm
output will operate normally for either of these displays. Refer to the relevant User’s Manual for details on the ranges for which control is
possible.
2. These errors are displayed only when the Controller is set to display the present value or the present value and the set value. They are not
displayed in other statuses.

Input error (See note.)
Check that the input wiring is correct, that there is no discon-
nection or short-circuit, and that the input type is correct.
(Thermocouple input short-circuits cannot be detected.)

After noting the error, reset the power. If the display does not
change, replacement is necessary. If the error is removed, it
is possible that the original error was caused by noise. Check
that there are no possible sources of noise.
