Address space for configuration as 1 x 8-channel DIQ 8x24VDC
The figure below shows the address space assignment for configuration as an 8-channel I/O
device with digital inputs/digital outputs without value status. The addresses of the channels
are derived from the start address.
Figure 5-2
Value status (Quality Information, QI)
The value status is always returned with the following configuration options:
• DIQ 8x24VDC/0.5A, QI
• DIQ 8x24VDC/0.5A, MSI/MSO
Evaluating the value status
An additional 2 bytes are occupied in the input address space if you enable the value status
for the I/O device. Bits 0 to 15 are assigned to a channel and provide information about the
validity of the digital input/digital output value.
Bit = 1: No error on channel.
Bit = 0: Error on channel.
