Creating a Project File
The following description provides information about how to create a project file to send the RUN command
and frequency references to three Inverters and read the Inverter status. ("PST" indicates the WS01-PSTF1-J
Protocol Support Tool.)
First, select from I/O items, monitor items, and parameters the data to be exchanged according to the applica-
tion. Then consider what sequence is required by using the protocol macro function.
Example: Writes control input items (such as the RUN command and multi-function input) of the Inverter and
frequency reference, monitors the control output (such as error output and RUN output) of the Inverter, and
monitors the Inverter status.
Three Inverters with Slave addresses from 01 to 03 are installed for communications.
Checking the Register Numbers
In the above example, the following three registers are required.
Control Input: Register 0001 Hex for RUN command
Frequency Reference: Register 0002 Hex
Control Output: Register 002C Hex for Inverter status
Memory Allocations
The PMCR instruction sends each Slave the data in consecutive words specified by the operand and beginning
with the first word (S), and writes in the memory area beginning with the first word (D) the data received.
The following memory allocations are made in the above example.
