Sub-Network Parameters - HMS Anybus Communicator User Manual

4.3 Sub-network Parameters

Communication
These parameters specify the actual communication settings used for the sub-network.
Parameter
Bitrate (bits/s)
Data bits
Parity
Physical standard
Stop bits
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>)
Parameter
End character value
Use End character
Start character value
Use Start character
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.
