•
Idle (bits)/DCD (msec) Period.
The meaning of this field depends on the chosen
transmission mode.
dcd
mode is the minimum idle time to resynchronize signal. It is
measured in units of time of 10 ms, and it is limited to a maximum value of 5.
idle
mode is the free-line time (unused) that is necessary for resynchronize after
detecting an error. It is measured in bit intervals, the value 0 not being allowed. To
deactivate the idle condition the value named
“IDLE time” (with a value by default
equal to 10) must be configured with a value equal to 0.
The new value equal to 0 will indicate to the GW104-101 that it must not consider the
standard idle times for eliminating messages.
5.9.3
RTU configuration
This submenu allows the identity parameters of the telecontrol remote (CA) to be
configured, and the operating parameters of the IEC 60870-5-2 link.

The configuration parameters are described below:
BALANCED RTUs:
•
#.
It establishes the equipment physical port number. Port 1 for port COM1.
•
Common Address Size.
It establishes the length of the address field that is to be
used by the remote in number of octets. The possible values are 1, 2 or 3.
•
Common Address.
It determines the telecontrol remote address.
•
Cause of Transmission Size.
It establishes the length of the CoT field that is to be
used by the remote in number of octets. The possible values are 1 or 2.
•
IOA Size.
It establishes the length of the field containing the address of the objects
in the remote in number of octects. The possible values are 1, 2 or 3.
