Determining Monitoring

Note If 8 characters are not needed in the message, input "0D" after the

last character.

The procedure below can be used to automatically set the monitoring time, T,

under actual operating conditions when specifying a word operand for T. This

operation cannot be used if a constant is set for T.

1. Switch the CQM1H to MONITOR Mode operation.

2. Connect a Peripheral Device, such as a Programming Console.

3. Use the Peripheral Device to turn ON control bit AR 2508.

4. Execute the program with AR 2508 turned ON. If the monitoring time cur-

rently in T is exceeded, 1.5 times the actual monitoring time will be stored

in T. FAL(06) errors will not occur while AR 2508 is ON.

5. Turn OFF AR 2508 when an acceptable value has been stored in T.

In the following example, the FPD(––) is set to display the bit address and

message ("ABC") when a monitoring time of 123.4 s is exceeded.

FPD(––) is executed and begins monitoring when LR 0000 goes ON. If LR

0015 does not turn ON within 123.4 s and IR 10000 through IR 10003 are all

ON, IR 10002 will be selected as the cause of the error, an FAL(06) error will

be generated with an FAL number of 10, and the bit address and preset mes-

sage ("10002–1ABC") will be displayed on the Peripheral Device.
