PRO-PRC
Quad Process Controller
This quad channel process controller is ideal for numerous industrial applications
with 0–20mA or 4–20mA DC inputs. It can be used either on its own, or inconjunc-
tion with another instrument (such as a transmitter).
One of the key features of this controller is its ability to average the inputs across 2,
3 or 4 input channels, and use this averaged value for a display source or for setpoint
activation.

Input signal in counts
Sampling
This feature allows signal averaging of each individual input channel, to optimise stable measurement. (This is dierent from Multi-Channel Averaging, which is set up in 5.3I.)
If the change in input exceeds the averag­ing window value it will not average, en­suring fast response when there are large dierences between readings.
Increasing the number of AVERAGING SAMPLES will stabilise measurement, but it will also slow down response rates.

E _ _ _ AVERAGING WINDOW scrolls across the display and toggles with the cur-
rently selected signal averaging window value. Using the and buttons,
alter the signal averaging window. Then press .
If your input signal contains large noise spikes, you can increase the size of the averaging win­dow to ensure that these are still averaged. However, increasing the window size too far will re­duce the ability of the controller to respond quickly to real changes in input signal. Setting AV-
ERAGING WINDOW to 0 will give continuous averaging as per the selected averaging samples.
F _ _ _ AVERAGING SETUP scrolls across the display and toggles with SKIP. You
are now back at 5.2C. To set up avarating for another input channel, proceeds through steps 5.2C–F again. To continue to 5.3, select SKIP and then press .

DISP will use the current display source (selected in 5.3B) for the peak/valley display. (If your display source [5.3B] is set to either 'PEAK' or 'VALLEY', then 'DISP' will not appear as an op­tion, as this would create a circular reference.) CH AVE will use the channel average value.
Peak and valley can be viewed or reset via the main display using the front panel shortcuts (see
2.3), or reset via the rear pins (see 3.6).
I _ _ _ SELECT NUMBER OF CHANNELS FOR AVERAGE DISPLAY scrolls across

APPENDIX A - SERIAL MODES
A.1 - Custom ASCII mode
Custom ASCII is a simple, custom protocol that allows connection to various PC con-
guration tools. ('Custom ASCII' diers from the 'Modbus (ASCII)' protocol used by
some devices.) Custom ASCII command strings must be constructed in this order:
<Start> <Controller Address> <Read/Write Command> <Register Address> <Separator Character> <Data Value> <Message Terminator>
Start - Use 'S' for the start character of a command string (not case sensitive). This
must be the rst character in the string.
Controller Address - Use an ASCII number from '1' to '255' for the controller address.
If the character following the start character is not an ASCII number, then ad­dress '0' is assumed. All controllers respond to address '0'.
Read/Write Command - Use ASCII 'R' for read, 'U' for unformatted read, or 'W' for
write (not case sensitive). Any other character aborts the operation.
In Custom ASCII mode, data is normally read as formatted (which includes decimals and any text characters that may be selected to show units). However it is also possible to read unfor­matted data by using a 'U' in the read command. There is no unformatted write command, as when writing to xed point registers, any decimal point and text characters are ignored.
Register Address - The register address for the read/write operation will be an ASCII
number from '1' to '65535'. This character must be specied for a write com-
mand, but may be omitted for a read command, (in which case the controller
will respond with the data value currently on the display).
Separator Character - The separator character can be either a space or a comma,
and is used to separate the register address from the data value.
Data Value - Must be an ASCII number. The absolute limits for this number are
1000000 to +1000000, but note that not all registers will accept this range.
Message Terminator - This is the last character, and must be either a '$' (dollar) or
an '*' (asterisk). Neither of these characters should be used elsewhere in the
PRO-PRC-MAN-17V01 (0802) Copyright © 2017 Dene Instruments
23
message string. If '$' is used, a 50ms minimum delay is inserted before a reply is sent. If '*' is used, a 2ms minimum delay is inserted before a reply is sent.
Custom ASCII Read/Write Examples
Example Description
SR$ Read display value from all controllers, 50ms delay.
S15R$ Read display value from controller address 15, 50ms delay.
S3U40* Read unformatted data in channel 4 from controller address 3, 2ms delay.
S2W2 –10000$ Write
SWT CHAN_1$ Write ASCII text string Chan_1 to channel 1 text register, 50ms delay.
10000 to the display register of controller address 2, 50ms delay.

Controller Response - Aer the controller has completed a read or write instruction,
it responds by sending a carriage return/line feed (CR/LF) back to the host. If
the instruction was a read command, the CR/LF follows the last character in the
PRO-PRC-MAN-17V01 (0802) Copyright © 2017 Dene Instruments
24
ASCII string. If it was a write command, CR/LF is the only response sent back.
The host must wait for this before sending further commands to the controller.
If the controller encounters an error, it will respond with a null (0x00) CR/LF.
A.2 - Modbus (RTU) mode
Modbus (RTU) is an industry standard RTU slave mode that allows connection to a
wide range of devices. Modbus registers are all holding registers, and should be ac-
cessed via function codes 3 and 6.
Register addresses are displayed in the Modicon™ 5-digit addressing format. I.e.
Register 65=400065 (subtract 1 for direct addressing).

A.3 - Ranger A mode
Ranger A is a continuous output, used to drive remote displays and other instru-
ments in the Rinstrum™ range. (Ranger is a trade name belonging to Rinstrum Pty
Ltd.) Ranger A output strings are constructed as shown:
<Start> <Sign> <Output Value> <Status> <End>
Start - STX character (ASCII 02)
Sign - Output value sign (space for + and dash for -)
Output Value - Seven character ASCII string containing the current output value and
decimal point. (If there is no decimal point, then the rst character is a space.
Leading zero blanking applies.)
Status - Single character output value status. 'U'=Under, 'O'=Over, 'E'=Error.
End - ETX character (ASCII 03)
