11.3 Sub-network Parameters
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 10 ms. 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 10 µs.
