Properties

Name BrowseName DataType Description
Maximum job size in bytes MaximumJobSizeInBytes UInt32 Maximum size of a transmission of tags from the controller (in bytes). 0 = 128 bytes (maximum value); different from 0: limits the maximum duration of transmission from the controller and the maximum latency of the writes to the controller following the reading to the set value
Maximum gap in bytes MaximumGapInBytes UInt32 Maximum distance in bytes between two tags to be part of the same transmission
Unit identifier UnitIdentifier Byte Device ID in accordance with the Modbus protocol specification
Write multiple coils WriteMultipleCoils Boolean Enables multiple write mode for Coil data
Write multiple registers WriteMultipleRegisters Boolean Enables multiple write mode for Holding Register data
IP address IPAddress String (TCP mode) Unique address to reach the controller on the network
Port Port UInt16 (TCP mode) Defines the number of the port used by the TCP-IP connection. It must match the one configured in the controller
Timeout Timeout Duration (TCP mode) Maximum wait time in milliseconds of the driver to receive a response from the controller
Tag optimization TagOptimization Boolean Enables/disables the grouping of multiple tags in a single read. If the controller doesn’t support the read multiple tags simultaneously mode, disable this option
Swap bytes SwapBytes Boolean This selection makes it possible to swap, for word-type data, the bytes between them. The result will be that the data linked between FactoryTalk Optix Application and device will swap the high byte with the low byte and vice versa, for each task word-type data
Swap Words SwapWords Boolean This selection makes it possible to swap, for double word-type data, the words between them. The result will be that the data linked between the FactoryTalk Optix Application and device will swap the word high with the word low and vice versa, for each task double-type data
Swap DWords SwapDWords Boolean
