Discrete Output Invert
0-on: it indicates a value of zero in
the corresponding do(1-8)
registers and generates an
inactive output (typically an
open contact).
1-on: it indicates a value of one in
the corresponding do(1-8)
registers and generates an
active output (typically a
closed contact). 1-on
5.7 RS-232 and RS-485 Options
Both, the RS-232 and RS-485 communications op-
tions provide network connectivity between a host
device, typically a personal computer, and the con-
troller via the Micro-DCI Datalink protocol.
Before communications can be established be-
tween the host and the controller, both devices
must be set for the same data rate and protocol
options. Controller communications parameters
for network connectivity are provided in the conF-
SYS module described in Table 5-13. The
Micro-DCI Datalink protocol is covered in Appen-
dix C.
The RS-232 or RS-485 communications module
plugs into the rear of the controller as shown in
Figure 2-12. It is secured to the backplane with a
single mounting screw.

Prompt Description (see Datalink prompts) Dft
iA Instrument Addrsss (Datalink)
It is the address assigned to this
controller on the datalink. Valid
addresses are from 0 - 31. No two
controllers can have the same
address on the datalink. 0
bAud Baud Rate (Datalink)
This value is set to match the data
transfer rate of the datalink. Valid
menu selections are:
110 4800
300 9600
600 19.2K
1200 14.4K
2400 28.8K
9600

Prompt Description (see Datalink prompts) Dft
dLE Datalink Enable (Datalink)
Selections are as follows:
on: Allows controller datalink
communication.
oFF: The controller is not permitted
to communicate over the
datalink. on
dLP Datalink Parity (Datalink)
Selections are as follows:
on: It indicates parity generation
and checking for even parity
serial byte protocol is enabled.
oFF: It indicates no parity protocol. on
dLS Datalink Stuffing (Datalink)
Selections are as follows:
on: Selects F&P byte stuffing, which
inserts a NULL (00) byte after
every SOH (7E hex) that is not
the beginning of a message.
This permits user written
communications software to
determine the number of bytes
to expect in a response
message.
oFF: Disables datalink stuffing. on
Not Communications Parameters
tAG Tag Name
Allows a 10 character tag to be
assigned to the controller. Four
characters maximum can be
displayed at any one time. Using
the engineer mode shift right push
button, the ten character positions
are displayed as follows:
0123
3456 6789
Characters are selected for each
position with the scroll
forward/backward push buttons.
b-FP
oPtA Contains an identification code
provided by the module resident in
slot A at the rear of the controller
case. Codes are as follows:
0: None.
192: 2DI/2DO module.
193: Single universal analog input
module.
194: Dual universal analog input
module. 0
oPtb Contains an identification code
provided by the module resident in
slot B at the rear of the controller
case. Codes are the same as for
oPtA above. 0
