USER MANUAL – Z-DAQ-PID

Operating modality
Description
Conversion with PID
The analog output is a function of the analog input
processed by the PID transfer function. Moreover, analog
output is directly proportional to the analog input
Conversion without PID
The analog output is directly proportional to the analog
input
Manual
(constant output without
PID)
The analog output is input-indipendent. Anyhow, the input
is acquired and can be found in the RS485 registers (only
reading)
Slew rate allows to limit the slope of the signal (see reg.40031 and 40032) and burn-out allows to
overwrite the OUT-Fault value (reg.40020, 40021) to the reg.40105, 40106 (burn-out overwriting
is available only for analog output).
Operating modality is configurable by software or by FunctionMod register (40007.[15:8]), with
refere
nce to the “RS485 registers table”.
There are two output type of Z-DAQ-PID, regardless of operating modality:
Out type
Description
Analog
OUT is an analog signal
ON-OFF
(see the following figures)
OUT is a ON/OFF signal. High state output is OUT-ES,
low state output is OUT-SS
If out type is “ON/OFF”, the Z-DAQ-PID module allows to have a ON/OFF output with activation
time t
ON
(time corresponding to the high-state output) directly proportional to OUT
L
.
To understand the ON/OFF out type functioning, see the following figure.
