Setting Jumpers - ProSoft Technology ControlLogix MVI56E-SMGC User Manual

MVI56E-SMGC ♦ ControlLogix™ Platform
Enhanced FMC722 TPU General Communication Module

1.2 Setting Jumpers

The Setup Jumper acts as "write protection" for the module's firmware. In "write
protected" mode, the Setup pins are not connected, and the module's firmware cannot
be overwritten. The module is shipped with the Setup jumper OFF. Do not jumper the
Setup pins together unless you are directed to do so by ProSoft Technical Support (or
you want to update the module firmware).
The following illustration shows the MVI56E-SMGC jumper configuration with the Setup
Jumper OFF.
Note: If you are installing the module in a remote rack, you may prefer to leave the Setup pins jumpered.
You can update the module's firmware without requiring physical access to the module.
Security considerations:
Leaving the Setup pin jumpered leaves the module open to unexpected firmware updates.
You should consider segmenting the data flow for security reasons. Per IEC 62443-1-1, you should align
with IEC 62443 and implement segmentation of the control system. Relevant capabilities are firewalls,
unidirectional communication, DMZ. Oil and Gas customers should also see DNVGL-RP-G108 for guidance
on partitioning.
You should practice security by design, per IEC 62443-4-1, including layers of security and detection. The
module relies on overall network security design, as it is only one component of what should be a defined
zone or subnet.
