QLength: 2 Registers (4 bytes)
QThis register has two bytes. Each byte has eight bits. The bits in these bytes are associated with the
status of the data received from the Analog Input Modules as follows:
QAnalog Input Module Data Status:
Abit value of 0 means that the data from this Analog Input Module is not yet valid. Either the
module is not present or has not yet been polled.
Abit value of 1 means that the data from this Analog Input Module has been polled at least once
and is valid.
Example:
Register 06112, Analog Input Modules Data Status, might contain the following data:
