The available parameters are described next:
Configuration
: as in the Linecoupler application program, this parameter
permits selecting a general preset for the mainline, or enabling the manual
configuration of each parameter (option “Configure”). However, the only
available preset in the Linerepeater application program is “Groups, Physical:
route (default option; performs no telegram filtering or dropping at all).
(The following parameters will be locked unless “Configure” has been
selected under “Configuration”).
Physical Telegrams
: sets the behaviour of the device regarding telegrams
destined to individual addresses. The available options are “Transmit all”
(default option; no telegram filtering or dropping) and “Block” (all telegrams
will be dropped).
Physical: Repetition if Errors on Main Line
: sets the desired reaction upon
transmission errors in the mainline (e.g.: busy receiver, acknowledgement not
received, negative acknowledgement, etc.) of telegrams destined to physical
addresses. The options are “No” (the undelivered telegram will not be re-
sent), “Normal” (the undelivered telegram will be re-sent up to three times)
and “Reduced” (default option; the undelivered telegram will be re-sent once).
Group: Repetition if Errors on Main Line
: sets the desired reaction upon
transmission errors in the mainline (e.g.: busy receiver, acknowledgement not
received, negative acknowledgement, etc.) of telegrams destined to a group
address. The options are “No” (the undelivered telegram will not be re-sent),
“Normal” (the undelivered telegram will be re-sent up to three times) and
“Reduced” (default option; the undelivered telegram will be re-sent once).
Telegram Confirmations on Line
: sets when the line repeater should
confirm (by sending an immediate ACK –or IACK– message) the reception of
telegrams. Selecting “If routed” (default option) will make the line repeater
respond with an IACK message only if the received telegram is routed
towards the sub-line, while “Always” will make the line repeater send a
confirmation for every telegram it receives, even if not routed to the line on
the other side.
