Alarm Input/Output - Panasonic WJ-MPU955A User Manual

Configuration

Alarm Input/Output

Alarm input and alarm output ports are used for alarm action purposes, and although each
has a specific function, both are configured within this section. Although the system
controller operator must control the I/O ports by logical number, these ports are viewable
within MPU955A Admin Console by both ID and logical port numbers.
Although I/O Ports may be assigned individually, the assignments must conform to the
following constraints.
Each GX encoder supplies 8 ports – 4 are input ports, 4 are output ports. Because of this,
4 consecutive Ports must be configured with the same directional type - either input or
output. For example, if Port 1 is configured as an input port, then Ports 2 - 4 must be
input ports as well. Then, another group of 4 ports may be configured as output ports. In
this manner, a maximum of 1024 GX ports may be defined, unless mixed with ports from
other node types.
Similarly, SX850 ports must be configured in groups of 8 with the same directional type.
Using the same example, if Port 1 is configured as an output port, then Ports 2 – 8 must
be output ports also. A maximum of 1024 (512 for Standard CPU size) SX850 ports may
be defined, unless mixed with ports from other node types.
SX650 ports are similarly defined in groups of 256 as input ports or groups of 64 as
output ports. A maximum of 1280 SX650 ports may be defined, unless mixed with ports
from other node types.
