4 Operation

Once the module has been configured, it will exchange HART information between

the HART field device and an EtherNet/IP controller (e.g. Logix), DNP3 Master,

Modbus TCP/IP client, or an SLC / MicroLogix / PLC5 using PCCC.

4.1 Logix 5000

When the module operates in a Logix “owned” mode the Logix controller will

establish a class 1 cyclic communication connection with the module. An input and

output assembly is exchanged at the configured (RPI) interval.

4.1.1 Input Assembly

The following parameters are used in the input assembly of the PLX51-HART-4I and

PLX51-HART-4O modules.

Table 4.1 – Logix 5000 input assembly parameters

Parameter

Datatype

Description

Instance

STRING

The instance name of the module

that was configured under the

general module configuration in

the PLX50 Configuration Utility.

Temperature

REAL

The internal temperature of the

module in °C.

Module

Status

DINT

Bit 0 – Configuration Valid
Bit 1 – Channel 0 Enabled
Bit 2 – Channel 1 Enabled
Bit 3 – Channel 2 Enabled
Bit 4 – Channel 3 Enabled
Bit 5 – Channel 0 HART Enabled
Bit 6 – Channel 1 HART Enabled
Bit 7 – Channel 2 HART Enabled
Bit 8 – Channel 3 HART Enabled

Channel Data
The next section is repeated for each of the 4 channels. Where x represents the channel number (0-3).
Chx_ManufacturerID

SINT

The unique manufacturer

identification code.

Chx_ManufacturerDeviceType

SINT

The device type code specified by

the manufacturer.

Chx_LiveList

INT

When using Multidrop

functionality this will indicate

which of the configured

devices are online. Note that

each bit represents the

configured Multidrop Device

Index (see the Multidrop

configuration in the Advanced

Mapping section).

Example: if bit 3 is set, then

Multidrop device at MD 3 is

online (for the specific

channel).

Chx_DeviceID

DINT

The device identification code

specified by the manufacturer.
