6.1. Module status word
When operating in cyclic mode, that is, polling values from the protection relay, the
module status word is transferred first in every message frame. The content of this
word includes the status of some important running conditions, as defined in Table
6.1.-1.
Table 6.1.-1 Module status word description
Bit Name Description
0 Gateway mode 0 = Gateway operates in configuration mode.
1 = Gateway operates in application mode.
1 Configuration status 0 = The configuration file is working properly.
1 = The configuration file has errors (CRC, incorrect setup detected…) or does not exist (first
start-up). For more information about the errors, see Section 8.4. Troubleshooting.
2 Hardware status 0 = The gateway is working properly.
1 = Hardware failures have been detected in the gateway.
3 SPA On-line (0) /
Off-line (1)
0 = Gateway is on-line. It communicates with the SPA slave device.
1 = Gateway is off-line. Communication with the SPA slave device is disconnected.
4 SPA initialized (0)/
Initializing (1)
0 = Configuration file has been initialized.
1 = Configuration file is being initialized.
5 Configuration Warning 0 = No errors detected during initialization of the configuration file.
1 = Errors were found while initializing the configuration file. The warnings do NOT prevent
the gateway from its operation state. Or, errors were found when the gateway tried to read
SPA parameter that does not exist in the SPA slave. Check template documentation for the
list of required functions in the SPA slave.

10 Indirect SPA pending This bit informs the state of message flow between the gateway and SPA slave. When using
the Indirect SPA messaging interface, this bit informs that the current message is pending
and waits for a SPA response.
11 Indirect SPA complete This bit informs the state of message flow between the gateway and SPA slave. When using
the Indirect SPA message interface, this bit informs that the current pending message is
complete.
12 Indirect SPA error This bit informs the state of message flow between the gateway and SPA slave. When using
the Indirect SPA message interface, this bit informs that the current message response
contains errors.
13 Reserved Bit used internally
14 SPA slave lost events The status information of SPA slave devices indicates that events have been lost.
15 SPA slave event buffer
overflow
Overflow. The status information of SPA slave devices indicates that an event buffer overflow
has occurred.
