Functions and Programming
1, 2, 3... 1. The limit warning mode is set with bit 09 of DM word m. This mode setting
applies to all 8 inputs.
Bit 15
DM (m)
Mode 1
The output values are compared to the upper/lower limits from startup.
Upper-limit value
Lower-limit value
ON
Warning
OFF
Flag
Mode 2
The output values are compared to the upper/lower limits after the output
value enters the range between the lower and upper limits.
Upper-limit value
Comparison start
Lower-limit value
Warning ON
Flag
OFF
2. The limit warning function is enabled with bits 00 to 07 of DM word m+3. Set
the corresponding bit to "1" to enable the limit warning function for that input.
Bit 07 06
DM (m + 3)
3. Set the upper and lower limits for each input in the corresponding pair of
words in DM m+28 through DM m+43. The data must be BCD from 0000 to
4000 and the upper-limit value must be greater than the lower-limit value.
The scaling function's upper/lower limits are used when the scaling function
is being executed.
