NOTE: the variables included in each of the previous tables are contiguous: it is possible to read
every variables with two request frames. With the first request frame the 28 words included in Table
4 can be read, with the second request frame the 2 words included in Table 5 can be read.
In order to know the current digital output settings, see the EEPROM map paragraph.
2.10 READING OF ALARM, DIAGNOSTIC AND REMOTE CONTROL OUTPUT STATUS
The n
th
digital output can work as pulse output, alarm output, diagnostic output or remote control
output.
In order to know if the n
th
digital output is set as alarm, the n
th
alarm byte (“alarm n”) must be read. If
the byte is equal to 0 it means that the digital output is not set as alarm, if it is equal to 1 the alarm
status is OFF, if it is equal to 2 the alarm status is ON.
The same considerations are valid in case of diagnostic output (“diagn n” byte must be read) or
remote control output (“Remote n” byte must be read).
Of course, only one among “alarm n”, “diagn n” and “remote n” byte can be different from 0. If all
these three bytes are equal to 0, it means that the n
th
digital output is set as pulse output.
