Block 4: Channel-specific diagnostics
Up to 10 channel errors are indicated here. There are 3 bytes per channel error, this block
can be a maximum of 30 bytes in size. Each channel error is an individual and independent
error. In order to display the channel errors, the I/O terminal must support PCP (Peripherals
Communication Protocol) and channel-specific diagnostics must be activated on the bus
coupler.
