*1 Do not perform the following tests.
When testing, the module may not operate correctly or the buffer memory/input
signal may return to the output value/output status from the special function
module.
1) Test the buffer memory for reading-only from the PLC CPU.
2) Test the input signal to the PLC CPU from the special function module.
*2 When testing buffer memory data, specify the change value in the following way.
1) For data where 16/32 bits is displayed with one number, specify the change
value in decimal.
2) For data where one number of 16/32 bits is displayed as a percent, such as with
an A/D conversion module, specify the change value corresponding to the
percentage in decimal.
Example:
When the set value of the offset or gain is 0 to 2000, when specifying a change
value of 50%, input 1000.
3) For data where 16 bits is displayed one bit at a time as "0" and "1", specify the
change value of 16 bits in decimal.
