7.10 Digital Output Loop (DOL)
The DOL OPC90 block is used to send an exception reported output generated
by updates to the block input tag (IN). The exception reports can be received by
a Bailey console digital tag, Bailey Digital Input / Loop blocks (function code 42)
nd Digital Input / Infinet blocks (function code 122). Note that this block does
