Communications Mode (RS-232C/RS-422)
The communications Mode can be set to RS-232C (default) for single axis applications with cable
lengths less than 35 feet, or to RS-422 for multi-drop applications or cable lengths longer than 35 feet.
Generic Operator Terminal
The Generic check box selects the use of any generic operator terminal for the serial port 1 connection
on P7. If this setting is cleared, the IQ Operator Terminal is selected. When a generic terminal is used,
the IQ will not automatically send any special characters to the serial port. PRINT and READ state-
ments can be used in a program to send any characters to the terminal. The built in status functions,
Xkey functions, and Fkey functions cannot be used with a generic terminal.
The Generic check box (available for Port 1 only) is used to specify a generic operator terminal. No
Allen-Bradley Operator Terminal control codes will be automatically sent to the terminal when using
PRINT, READ, and CLEAR commands if this box is selected. Control codes can still be sent to your
terminal using the PRINT "^code" statement, however. The Generic option is available only in firm-
ware versions 2.10 and later. If your firmware version is earlier than 2.10, the check box will be dis-
abled.
If a generic operator terminal is used, the Op Term Key and the Codes list boxes are used to specify the
codes the operator terminal generates. Select the specific key from the Op Term Key list box, then select
the code for the key in the Codes list box. The code consists of two bytes--the high byte being the left
most Code list box. If your codes are in hexadecimal, you must convert to decimal. For example, if the
generic terminal sends ’5Fh 0h’ for F1 ON and ’6Fh 0h’ for F1 OFF, select ’95 0’ for F1 ON and ’111 0’
for F1 OFF. If the operator terminal sends only single byte codes, set the high byte of each key code to
0.
For keys that are not implemented, the key code should be set to 0. The Generic check box must be
selected and the code for F1 ON must be non-zero so that the IQ will load the key codes on power up.
The Generic check box does not have to be selected to set the key code values, however. If the operator
terminal does not support the F1 ON function, a code that will never be sent must be set for the F1 ON
code value. This option is available only in firmware versions 2.11 and later. If your firmware version is
earlier than 2.11, the list boxes will be disabled.
Operator Terminal Address
The Operator Terminal Address box is used to specify a unique address (range is 0 to 9) which is used
when the Operator Terminal is used in a multi-drop application. (To use the Operator Terminal in multi-
drop mode, the Operator Terminal and the IQ must be wired for RS-422 and Port 1 must be set to RS-
422 mode.) Each IQ connected to the Operator Terminal in the multi-drop mode must have a different
address assigned. Address 0 is automatically selected on power up. To communicate with a different IQ
from the Operator Terminal, press the ’NO’ key on the Operator Terminal followed by the desired
address (0-9). This option is available only in firmware versions 2.12 and later. If your firmware version
is earlier than 2.12, the box will be disabled.
