Communicating with Modicon PLC
Each Modicon PLC comes with a Modbus port. The
control program can read/write the settings from/to
the P520/P522 scanner via this port. A XMIT
loadable module is needed to send Modicon func-
tions. XMIT loadable module is available from
Modicon Inc.
Note: Not all models of Modicon PLC’s
will accept the XMIT loadable module.
Please consult you local Modicon dealer
for more information.
Communication with Human-Interface
Host Computer
A number of Modbus drivers for Microsoft Window
95 and NT are available from the third party devel-
oper, such as Rockwell Software’s WinTelligent
Linx Modicon. A Modicon driver allows applica-
tion programs such as Microsoft Excel, Wonderware
and RSView to communicate with the P520/P522
scanners directly.
RS-232 to RS-422 CONVERSION
It is necessary to use a RS-232 to RS-422 converter
at the host computer. The IRIS COMM converter
module can be used, and is recommended because
of its photocoupler isolation. The converter must
have galvanic ground isolation.
SETTING ADDRESSES
Each P522 must have its own unique address. The
address is easy to change. Press the RESET push-
button for >2 seconds, causing the P522 to immedi-
ately display its address on the four-digit display
(0000 to 0063), and change using the UP or DOWN
arrow buttons. When the desired address is dis-
played, push the STORE button, and the P522 will
immediately respond to this new address.
In current software revisions of the processor (ver-
sions 3.0 and higher), the baud rate can also be changed
when the module address is changed. The baud rate
is displayed in the highest two digits of the numeric
display (i.e., 4802 is 4800 baud and address 2). To
change to 9600 baud, increase the display past 4863.
The next display will be 9600, which is 9600 baud,
address 0. Then increase the display further to the
desired address. To return to 4800 baud, reduce the
display below 9600, and set the desired address.
