Table 11.1 Supported data transfer formats
The data format 8E1 with even parity (E=even) corresponds to
the PROFIBUS-definitions according to DIN 19245, part 1, and is
supported by the datalogger both in the PROFIBUS-protocol and
in the ASCII- and MODBUS-protocol. This data format should
therefore generally be selected for the transmission.
For modem connections, which in most cases can be carried out
without a parity-bit, the second data format is available. This data
format is only supported by the ASCII-protocol and the MODBUS-
protocol.
The data format is defined via configuration software
COMBILOG.EXE
. If there are no other specifications, the default
adjustment is ”no parity”.
