PROTOCOL (when "Use PLC" is disabled)
The PROTOCOL screen is used to set “Handshaking protocol” and various items
to enable the "Use PLC".
1. When “Use PLC” is disabled, set the “Handshaking protocol” as shown above.
2. Select “Header” and “Delimiter” from the displayed items. You can change the
read data format by setting these items. If you select “Custom”, the following
screen appears. These items can be set to any five character string using the
keyboard.
Note: When customizing the header and delimiter, you modify them based on the
previously selection. When selecting "custom," if you currently use "CR", "0D"
appears in hex and "." in ASCII (It is not a period but stands for "CR"). If "none"
was used previously, nothing appears.
3. Normally, the ID number of the BL series that executed reading is not added to
the read data in multi-head scan mode. However, you can set “Add ID” so that
the ID number is added to the read data.
4. “Checksum” can be added to read data to check incompatible data translation
between the N-400 and the host computer. Normally, this function is not neces-
sary.
