Instructions

• Error check type: Specify how the checksum is converted. Select None (Default), One’s complement or Select
None, Two’s complement.
• Representaon: Specify how the checksum is represented. Select Binary (Default) or ASCII.
About Fixed eld*
• Yes, set here: The Value set here is xed and cannot be changed when the transacon is used on a node.
The value must be updated in the transacon template.
• No, set when used: The Default value set here can be edited when the transacon is used on a node.
The allowed range is the min/max values.
Total size including delimiters:
• High Level Network: 1 byte(s)
• Subnetwork: 1 byte(s).
4. Repeat step 1 to 3 unl you have congured all the desired frame objects.

7.7.4. Data Delimiter and Subnet Delimiter Opons
In a variable data object, the length of the data eld may vary depending on the type of data being read in a
specic case.
In order to present the variable data correctly on the corresponding network, the length of the data eld must be
idened.
In a Variable data object, there are three ways to idenfy the data length; by length character, end character or
length of message.
Data delimiter - Data is forwarded From the Communicator to the PLC
The Communicator can be congured to forward data as process data.
Dierent Data delimiter opons can be used for data sent from the subnetwork to the Communicator and for
data forwarded from the Communicator to the high level network, to t the requirements in the PLC.
In most cases, when a stream of data is sent from the Communicator to the PLC the Byte counter (length
character) or End paern (end character) format is used.
Subnet delimiter - Incoming Data From a Serial Node to the Communicator
The Communicator can be congured to expect data from one of the three Subnet delimiter opons; Byte
counter, End paern or None.
If the incoming data match the Subnet delimiter format the data is captured and the data secon is forwarded to
the high level network.
If the incoming data do not match the Subnet delimiter format, the data is ignored and will be matched with the
next consume transacon.
