I/O and Hardware (M5)
● Logical Analog Input (LAI) – a floating or multi-state input for status.
● Logical Analog Output (LAO) – a floating or multi-state output for commanding.
Each point type supports Change of Value (COV) reporting based on the point's present value, priority, and status
(failed or normal). The output points are typically commandable from the P1 master panel where the input points
are for monitoring purposes only.
If Protocol (5.8.1.1) is set to a value of P1, then configuration and status parameters related to the P1 fieldbus
protocol are made available.
Parameters (M5.8.3.1)
The following configuration parameters are available for the P1 fieldbus protocol:
Menu Parameter
P5.8.3.1.1 Slave Address
P5.8.3.1.2 Baud Rate
P5.8.3.1.3 Communications Timeout
Monitoring (M5.8.3.2)
The following monitoring values are available for the P1 fieldbus protocol:
Menu Parameter
M5.8.3.2.1 Fieldbus Protocol Status

Faulted Displays the current protocol status as follows:
0 = Initializing – Protocol is starting up.
1 = Stopped – Protocol is timed out or not in use.
2 = Operational – Protocol is running normally.
3 = Faulted – Major fault in protocol, requires restarting. If
fault remains, contact Technical Support.
Description
Defines the unique slave address to
be used by the drive on the P1
network. Broadcast messages are
sent to device number 99 and all
devices on the network respond to this
address; therefore, address 99 is a
reserved address and cannot be used
on any device on the network.
Defines the communications speed on
the network which must match all
devices on the network. Possible
settings are:
1 = 4800
2 = 9600
Defines the amount of time in which a
packet is not received from the master
before a communications timeout is
faulted/alarmed. A setting of 0 means
that no fault is generated.
