Seneca Z-PC Line module: Z-DAQ-PID

The Z-DAQ-PID module acquires one universal input signal (voltage, current, potentiometer,
thermo-couple, thermo-resistance, m-voltmeter) and converts it to an analog format (with PID
regulation).

General characteristics

 Three operating mode: conversion with PID regulator, conversion without PID regulator, manual

(constant output configurated through ModBUS register)

 Two output types: analog or ON/OFF (time of high-state digital signal is directly proportional to

the analog signal)

 Universal input: voltage, current, potentiometer, thermocouple (TC), RTD (Resistance

Temperature Detector) , m-voltmeter

 Analog Output: voltage type, active current type, passive current type
 Slew-rate, burn-out, output limiters setup
 Modbus address and baudrate configurable by Dip-Switches

4. Operation Modes

There are six possible functioning modalities for the Z-DAQ-PID, with reference to the following
figure:

- conversion with PID, analog output

- conversion with PID, ON/OFF output

- conversion without PID, analog output

- conversion without PID, ON/OFF output

- manual (constant output), analog output

- manual (constant output), ON/OFF output
With reference to the following figure, the lowest part shows the Z-DAQ-PID setting procedure in

three steps: input setting, operating modality setting, output setting.

In particular, there are three operating modes, each of them allows to supply a ON/OFF output or
an analog output:

USER MANUAL – Z-DAQ-PID

8

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)

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

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
reference to the “RS485 registers table”.

There are two output type of Z-DAQ-PID, regardless of operating modality:

If out type is “ON/OFF”, the Z-DAQ-PID module allows to have a ON/OFF output with activation
time tON (time corresponding to the high-state output) directly proportional to OUTL.

To understand the ON/OFF out type functioning, see the following figure.

USER MANUAL – Z-DAQ-PID

9

It is possible to limit upper time of high-state ON/OFF output (reg.40029) and to limit lower time
of low-state ON/OFF output (reg.40030). The cycle time is reg.40028 (constant frequency of
ON/OFF output=1/cycle time).

CONVERSION WITH PID

In “Conversion with PID” operating mode, the output (analog or ON/OFF) is a function of the

analog input processed by the PID transfer function. Moreover, output is directly proportional to
the analog input.

PID regulation allows to incline input signal PV (process value) to SP (set point value) with
particular properties (rise time, overshoot, steady-state error, settling time, etc…). In the following
figure is shown the Z-DAQ-PID module used as PID.

In particular, “e” means the difference between set-point and process-value:
Signal error e = (process value – set point) means PID regulation direct-type (for example: used

for cooling)
Signal error e = (set point – process value) means PID regulation reverse-type (for example: used

for heating)
The PID regulation is described by the following parameters:

where Tsample means the PID sampling time (it is equal to 100ms).

7. Modbus RTU protocol

All registers are “Holding register” (Read Modbus function 3) with the convention that the first register is

the 40001 address.

The following Modbus functions are supported:

Read Single Modbus Register (function 3)

Write Single Modbus Register (function 6)

Write Multiple Modbus Registers (function 16)

All values in 32bits are stored into 2 consecutive registers, for example:

If a floating point 32 bits is stored into registers 40135 and 40136, the Most significant word is the register
40135, the less significant word is the 40136.

So the 32bits value is obtained by the following relation:
