Sample Transmission Data with Header/Footer and ASCII Conversion
Specified
The Personal Computer Link module is normally used with the PC link function. When
transmitting event data in the midst of exchange of PC Link commands and responses,
it may be easier for the higher-level computer to get such data if the data format
matches the format of PC Link responses. This can be achieved by attaching a
header/footer.
The sample transmission data shown below assumes that output relays
Ylmm37/Ylmm53 (Specify Header/Footer) and Ylmm38/54 (ASCII conversion) are used.

* The checksum and CR are only added if they are enabled using the SW2 setting or software setting.
