Digital I/O
10.1 Discrete inputs/outputs
Entellisys provides support for up to 128 discrete I/O points that can be configured as either
inputs or outputs. Purchase of separate hardware is required. Discrete I/Os are controlled by the
FlexLogic™ program (see
). Their functionality can be divided into two
separate components: hardware and software, described in the corresponding sections below.
10.1.1 Hardware
Slots PMC0 and PMC1 on the CPU board each accommodate one discrete I/O board. Hardware
requirements also include an “OR” board, relays and relay blocks, described in detail in the
corresponding sections. Discrete I/Os can be wired in two distinct configurations. One
configuration allows for redundancy of discrete I/Os and the other that is non-redundant. The
latter configuration can be used when uptime and reliability is not as important. These
configurations are described in corresponding sections below.
