Product Selection Guide
Modbus TCP, RTU or ASCII require software license OP3262, which comes with 50 data points (visit this page more information on data points). If additional data points are required, then they may be added via product OP3050.
Modbus TCP
Modbus TCP can be added to real-time simulators without the need of additional hardware. However, since real-time simulators come with at least one available ethernet port, if additional physical ethernet ports are required on the real-time simulator, these can be added via kit. Note that for applications requiring many ethernet ports, the OP4510 platform is not recommended.
Modbus RTU
For Modbus RTU, applications requiring RS-232 are supported natively by real-time simulators with one serial port. If RS-485 or additional RS-232 ports are required, then a BLG-series Bluestorm PCI module must be added to the system. Due to the form factor of the Bluestorm modules, they are only compatible with OP5600, OP5700 and OP5000-series simulators. Hence, for applications requiring RS-485 or multiple RS-232 ports, the OP4500-series platform is not recommended.
Modbus ASCII
Modbus ASCII applications require the use of an external gateway (EKI-1221-CE) to convert Modbus TCP to Modbus ASCII.
