5.1.4 Count cycle changing 
This section describes how to change the count cycles of the sampling pulse number 
and accumulating count value. 
 
To change the count cycle, set "1: Count cycle change function selection valid" in the 
"count cycle change function selection" of the buffer memory. (Whether the function is 
valid or invalid can be selected on each channel.) 
Further, set the count cycle in the "count cycle setting value" of the buffer memory.

*: When "count cycle change function selection invalid" is set, the count cycle is 1s 
(fixed). 
 
 
POINT 
 
•  If the setting value is other than the above values, a count cycle setting range 
outside error (error code: 600) occurs. To clear the error, turn ON the error reset 
request (Y8 to YF) of the corresponding channel. After this, set a correct value 
and then turn ON the operating condition setting request flag (Y1). 
•  The settings are reflected on the module by turning ON the operating condition 
setting request flag (Y1) after setting the values to the buffer memory.
