Analog Elements
Analog input Analog output number
Analog input A 8 (A01~A08)
Analog input parameter V 8 (V01~V08)
Temperature input AT 4 (AT01~AT04)
Analog output AQ 4 (AQ01~AQ04)
Add-Subtract control AS AS 31 (AS01~AS1F)
Multiply-Divide control MD MD 31 (MD01~MD1F)
PID control PID PID 15 (PI01~PI0F)
Data Multiplexer control MX MX 15 (MX01~MX0F)
Analog Ramp control AR AR 15 (AR01~AR0F)
Data Register DR DR 240 (DR01~DRF0)
MODBUS 15 (MU01~MU0F)
Analog value (A01~A08, V01~V08, AT01~AT04, AQ01~AQ04) and current value of functions (T01~T1F,
C01~C1F, AS01~AS1F, MD01~MD1F, PI01~PI0F, MX01~MX0F, AR01~AR0F, and DR01~DRF0) can be used as
other function’s preset value. And the parameter preset value is its limit value when the current value of those
functions is bigger or less than parameter’s limit value.
