DH+/RIO OPTICAL COMMUNICATION MODULES USERS MANUAL

Read/Write Diagnostic Status and Control functions are given in the Diagnostic I/O Bit Map illus-

trated in Figure 9. Definitions of Diagnostic/Configuration Select Switch Settings are provided in

Table 11. Specifications and further explanation of OLC diagnostic functions are provided in Sec-

tions 1.3.3.5-1.3.3.10.

1.3.3.4 1756 PLUG-IN OCXs (Modules with “-D” Diagnostic Option Only)

Monitoring of 1756 Plug-In OCX module diagnostics is provided thru a read status register in the

PLC Processor I/O memory. The 1756 Plug-In OCX module (with “-D” Option) occupies a single

I/O module slot, and simulates a 16 bit input module, addressable to the 1756 I/O module slot it

occupies. Diagnostic function control is provided via Diagnostic Select Switch Settings. (OCX

modules without the “-D” diagnostic option do not have a 1756 bus interface and appear as empty

slots to the processor.)

RSLogix 5000 OCX I/O module configuration is similar to other types of 1756 I/O modules. The

first step is to confirm the OCX module is “Offline”. Next open the “Select Module Type” configu-

ration screen, and select from the list given on the screen the I/O Module Type/Description... “1756-

Module Generic 1756 Module”. This will create a new module “Module Properties” configura-

tion screen. In the “Module Properties” configuration screen, the user must select the “General” tab

and enter and/or select the following I/O module configuration information:

Name: OCX_DPR_x *

Description: Optical Comm Module

Comm Format: Data - DINT

Slot: The I/O slot # where the OCX is located.

Connection Parameters

Assembly Size:

Instance:

Input: 130 2

Output: 197 1

Configuration: 1 8

* Each OCX module must have a unique Name, so that each I/O module in the

I/O configuration can be individually identified and located by RSLogix I/O

configuration software. Therefore, in the example given above, the Name field

“OCX_DPR_” is followed by a variable field “x”, and this field should be

designated by the user as a number (ie. 1, 2, 3, 4, 5, etc.) or letter (ie. a, b, c, d, e,

etc.) so that each OCX-DPR module present in the I/O configuration will have a

unique name.
