Maple OIT Communication with Siemens SIMATIC TI305 Series PLC





The Maple OIT should be connected to the communication port located on the CPU module of the OLC or through the Data Communication Module (DCU). A Siemens cable assembly is required for connection of the OIT to the PLC.

Maple OIT is compatible with Siemens SIMATIC TI305 Series which the PLC models are TI335, TI330, and TI325.

Some versions of the Siemens SIMATIC TI305 PLC have a turnaround delay setting which is set either in the DCU module or in the data register. Because the setting affects communications speed with the OIT, it should always be set to 0. The password must match the Password setting in OITware.

The following table lists the PLC register memory ranges that Maple’s OITs are able to access. Your PLC’s memory range may be smaller or larger than that supported by Maple’s OIT. The below PLC register memory is displayable in 16 bit or 32 bit format.
