Configuration of Communications Port
(Address Block 7200)
The device provides one or two serial interfaces: one
PC interface in the front for operation by means of a
PC and depending on the model ordered, another
system interface for connection of a central control
and storage unit, for example Siemens LSA 678.
Communication via these interfaces requires some
configured settings: identification of the relay,
transmission format, and transmission speed.
• 7209 DEVICE. TYPE
- Identifies the device type of the relay to
Siemens LSA systems and to WinDIGSI
software. Usually this setting should not be
changed.
• 7211 FRONT PORT
- Data format for communication via the
front-panel data port.
• 7215 FRONT BAUD
- Data transmission rate for front-panel data
port.
•7216FRT. PARITY
- Data parity setting for front-panel data port.
• 7221 REAR PORT
- Data format for communication of Operational
Log and fault logs via the rear data port (on
the back of the relay case).
• 7222 REAR FORMAT
- Data format for communication of measured
values via the rear data port (on the back of
the relay case).
• 7225 REAR BAUD
- Data transmission rate for rear data port (on
the back of the relay case).
• 7226 REAR PARITY
- Data parity setting for rear data port (on back
of the relay case).
• 7235 PROGviaREAR
- Choice of whether relay will allow
configuration via the rear data port (on the
back of the relay case).
