D (m+10)
Loop 1
Alarm 1 SV
Set in 4-digit BCD or 16-bit binary.
The values written here are written to RAM.
When the BCD data format is being used, the most signifi-
cant digit indicates the sign. (F represents the “
−
” sign.)
D (m+11)
Alarm 2 SV
D (m+12)
Input Compensation Value Set in 4-digit BCD or 16-bit binary.
The values written here are written to RAM.
When the BCD data format is being used, the most signifi-
cant digit indicates the sign. (F represents the “

D (m+13)
Control Period
Set in 4-digit BCD or 16-bit binary.
The values written here are written to RAM.
D (m+14)
Control Sensitivity
Set in 4-digit BCD or 16-bit binary.
The values written here are written to RAM.
This setting is valid with ON/OFF control only.
D (m+15)
Proportional Band
Set in 4-digit BCD or 16-bit binary.
The values written here are not written to RAM while the PID
Constants Calculated Flag is ON.
The values written here are written to RAM.
These settings are valid with PID control only
