Rockwell Automation 1336-GM1 Remote I/O Communications Module - Manual (Page 3)

Summary of Changes
The information below summarizes the changes made to this manual
since the last release.
Updated Information This manual incorporates the information found in the following two
manuals:
•
Bulletin 1203 Remote I/O Communication Module Getting
Started Manual, Publication 1203-5.1.
• Bulletin 1203 Remote I/O Communications Module Reference
Manual, Publication 1203-5.0.
It also contains new information.
Updates and Additions The information below summarizes the changes to this manual since
its last release:
Page Description
2-5 Important statement added:
Injury or equipment damage can result from loss of PLC or Controller Logic
Commands (Stop, Start, etc.) when all these conditions are true:
- module firmware 3.04 or lower.
- 230.4k baud rate.
- block transfer is enabled (DIP switch SW3-1 is ON).
- block transfers to the module are used (in the ladder program or by DriveTools/
DriveTools32 using a Remote I/O pass thru connection).
Do not use the 230.4k baud rate if you are using a module with 3.04 or earlier
firmware and your program uses block transfers. Use the 57.6k or 115.2k baud
rate instead.
2-6 Attention statement added:
Due to an anomaly in firmware release 4.01, Remote I/O modules that are used
only for block transfer messages require the following configuration: switches for
block transfer and reference/feedback should both be enabled (SW 3.1 and SW
3.3 are ON. SW 3.2 and SW 3.4 through 3.8 are OFF).
This configuration prevents a fault on power up. It does not affect rack I/O
allocation or the ladder logic program because it still fits within 1/4 rack I/O space.
The drive will, however, generate a serial fault if the communications module is
disconnected or loses power.
