Sub-Network Parameters
(To gain access to the parameters described in this section, select ‘Sub Net-
work’ in the Navigation Section).
Communication
These parameters specify the actual communication settings used for the sub-network.
Start- and End Character
Note:
These parameters are only available in Generic Data Mode.
Start and end characters are used to indicate the beginning and end of a serial message. For example, a
message may be initiated with <ESC> and terminated with <LF>. In this case, the Start character would
be 0x1B (ASCII code for <ESC>) and the End character 0x0A (ASCII code for <LF>)
Timing (Message Delimiter)
The parameters in this category differs slightly between the different Protocol Modes.
• Master Mode
The Message Delimiter specifies the time that separates two messages in steps of 10ms. If set to
0 (zero), the gateway will use the standard Modbus delimiter of 3.5 characters (the actual number
of ms will be calculated automatically based on the currently used communication settings).
• Generic Data Mode
The Message Delimiter specifies the time that separates two messages in steps of 10µs.
