The status word written to the tag specified in the destination field of

the MSG instruction is defined as follows:

Get 1769 I/O Module Configuration Size

1769 I/O modules should be configured in RSNetworx for DeviceNet

when your DeviceNet system is configured. We’ll describe how to

modify 1769 I/O module configuration parameters while the system is

running. Modifying I/O module configuration parameters dynamically

is not a common practice, but for some applications it may be

necessary.

We’ll use a 1769-OF2 analog output module to get/set configuration

parameters dynamically for this example.

The first task is to determine the size of the configuration file for the

1769 I/O module. The following command will read the number of

configuration words (not bytes) from the 1769-OF2 in slot 10 of the

remote DeviceNet system by sending a CIP Generic message to the

1769 I/O module via DeviceNet. One word will be read from the 1769

I/O module which contains the word count of its configuration file.

Bit Description

0 0 = No module error detected

1 = Module detected error present

1 0 = Communication on bus OK

1 = Communication Fault on bus

2 0 = Module is not configured

1 = Module is configured

3-7 Reserved, set to 0
