Status Reporting
The ECM850 provides 32 bits of status information to a configured location in the RX3i
CPU’s reference
memory.
The status data consists of the Module OK bit, which indicates the health of the module
itself, a status bit for each external port, and a bit that indicates the connection status of the
configured devices.
All Status bits are active high. The status location may be configured in %I, %Q, %AI, %AQ,
%R, %G, %T, %M or %W or I/O Variable reference memory in the RX3i CPU.

Description
1
Module OK
Indicates the health of the ECM850.
1 indicates the module is functioning properly.
0 indicates the module is powering up or has failed.
2
Port1 Link Up
1 indicates the port is connected to another device and is operating
correctly.
0 indicates the port is not connected to another device or has an error
preventing communications.
3
Port2 Link Up
1 indicates the port is connected to another device and is operating
correctly.
0 indicates the port is not connected to another device or has an error
preventing communications.
4
Port3 Link Up
1 indicates the port is connected to another device and is operating
correctly.
0 indicates the port is not connected to another device or has an error
preventing communications, or the SFP cage is empty or has an
incompatible SFP device.
5
Port4 Link Up
1 indicates the port is connected to another device and is operating
correctly.
0 indicates the port is not connected to another device or the port has
an error preventing communications, or the SFP cage is empty or has an
incompatible SFP device.

1 indicates Protocol outputs are disabled and outputs are not sent on
the wire over the protocol
0 indicates Protocol outputs are enabled and outputs are sent on the
wire over the protocol

†
Individual device status (as reported by the Health status variable for individual IED) are
updated prior to the All Devices Connected bit. Therefore, it is possible (depending on ECM850
loading) to see via the Health status variables that every individual device is connected while the All
Devices Connected bit is not yet set. To avoid this inconsistency, it is recommended that the All
