KEYENCE BL-180 - Manual (Page 104)

Power Supply BL-U1

Example: When the command to shift to the setting mode (SSET) is sent to the BL series
of ID No. 3:
1. From the host computer:
2. Loopback data:
3. From the BL series:
If an incorrect ID number is specified, an incorrect format is used to send a com-
mand, or a data transmission error occurs (checksum is incorrect), the BL series
sends back no response. You will need to design a program so that the same
command is sent again (Retry) if the BL series sends back no response within a
specified period (Timeout).
With RS-232C or RS-422A communication, the BL series sends back no data in
response to some of the direct control commands (e.g. LOG<CR>). With the mul-
tidrop link, however, the BL series sends back the following data in response to
those commands.
During normal processing: OK
When error occurs: ERR**
** indicates an error code (see p. 70).
