Operation Control Commands
The following procedure is used to control the Unit.
Output word
Input word
1. Output word: An operation control command (Cjjjj) is set to specify the
loop and the operation.
2. Input word: The operation control command set in the output word will be set
as a "Command Acknowledged Flag" to indicate that the command has
been acknowledged.
Note The value set by the previous command will be valid as soon as the next com-
mand is acknowledged.
Command
(Set in output word;
see notes 1 and 2.)
CCCj (j = 1 to 4 or A)
CCDj (j = 1 to 4 or A)
CDCj (j = 1 to 4 or A)
CDDj (j = 1 to 4 or A)
CFCj (j = 1 to 4 or A)
CFDj (j = 1 to 4 or A)
CEEA (See note 6.)
Note 1. The Unit will start in Auto Mode in STOP status when power is turned ON.

2. Input the loop number for j in the command codes. "A" is used to indicate all
loops. When "A" is used, the operation control command will not be
executed for any loops if even one of the four loops does not meet the write
conditions. For example, a setting error will occur (EE01) if the AUTOTUN-
ING command is set when loops 1 to 3 are in RUN status and loop 4 is in
STOP status.
