High-Performance Connectivity for Toshiba Serial Devices
This driver is only available as part of the following TOP Server driver suites:
Max Devices per Channel (T3/T3H)
Series Supported (EX100/200/500, T1/T2/T3)
Serial Interfaces (RS-232/422/485)
Memory Types Supported
The Toshiba Serial Driver works in conjunction with TOP Server® to provide data exchange between OPC UA, OPC DA, SuiteLink and DDE clients and EX100/200/500 and T1/T2/T3 PLCs using the Toshiba ASCII Computer Link Protocol over Serial or Ethernet Gateway/Terminal Server connections.
Data acquisition is optimized based on upstream client demand while data integrity is ensured using extensive error handling.
Proven benefits for reliable Toshiba PLC serial connectivity
Direct serial communication with Toshiba PLCs via RS-232, RS-422 and RS-485 interfaces
Optimized polling based on client subscriptions for responsive monitoring and control
Connect to multiple Toshiba controllers simultaneously over serial networks
Ideal for environments requiring serial connectivity to existing Toshiba installations
"Outstanding reliability and performance. This driver has been running flawlessly in our production environment for over a year."
