seconds).
Bit 3 This bit makes available a clock impulse of 1
second (ON for 0,5 second, OFF for 0,5
second)
R
Bit 4 This bit is clock of scanning cycle, which is
active ON for one cycle and desabled OFF for
following cycle. It may be used as counting
input for scanning cycle.
R
Bit 5 Bit TEST. Setting this bit as ON, the reading
of digital inputs is desabled. Status of inputs
is read on words SM8 and SM9. Setting these
words, it is possibile to execute debug/test of
program simulating the starting.
R/W
Bit 6 This bit is ON during the transmission of data
to serial port COM1. It is automatically set to
OFF at the end of transmission
R
Bit 7 -
Bit 8 This bit is ON during the transmission of data
to serial port COM2. It is automatically set to
OFF at the end of transmission.
R
Bit 9 If set to ON this bit enables mode “modem” for
serial port COM1. This means that Timeout
between one character and the other
character in receiving mode is automatically
set to 40mS.
R/W
Bit 10 -
Bit 11 If set to ON this bit enables mode “modem” for
serial port COM2. This means that Timeout
between one character and the other
character in receiving mode is automatically
set to 40mS.

Bit 1 -
Bit 2 This bit is ON in case that the retaining data of
the area EEPROM are lost.
R/W
Bit 3 This bit is ON in case that calibration data are
lost

Bit 4 This bit is ON in case of CPU reset or of
watch-dog intervention
