Rockwell Automation 1336-GM1 Remote I/O Communications Module - Manual (Page 9)

Using This Manual P–3
Safety Precautions
!
ATTENTION: Only personnel familiar with SCANport
devices and associated machinery should plan or implement
the installation, start-up, configuration, and subsequent
maintenance of the Remote I/O communications module.
Failure to comply may result in personal injury and/or
equipment damage.
!
ATTENTION: The 1336-GM1 board contains Electrostat-
ic Discharge (ESD) sensitive parts and assemblies. Static
control precautions are required when handling this assem-
bly. Component damage may result if ESD control proce-
dures are not followed. If you are not familiar with static
control procedures, refer to Allen-Bradley Publication
8000-4.5.2, Guarding Against Electrostatic Damage or any
other applicable ESD protection handbook.
!
ATTENTION: 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.
!
ATTENTION: Hazard of equipment damage exists. If
block transfer messages are programmed to frequently
write parameter data, the EEPROM (Non-Volatile Storage)
will quickly exceed its life cycle and cause the product to
malfunction. Do not create a program that frequently uses
block transfer messages to write parameter data to a
product. Datalinks do not write to the EEPROM and should
be used for frequently changed parameters.
!
ATTENTION: Hazard of equipment damage exits.
Firmware version 3.04 has the following anomaly: If DIP
Switch 2-5 is OFF (No Fault), the product remains in its last
state after a communications loss occurs no matter how DIP
Switch 2-4 is set. If you must use zero data, contact
Rockwell Automation Technical Support.
