Ethernet Communications

Using EtherNet/IP™

Communications To/From Third Party Device:

When using the EtherNet/IP protocol, there are two

methods used in communicating, implicitly and ex-

plicitly. Once the gateway instance is enabled there

are two prompts that relate directly to these forms of

communication.

Use the graphic below in reference to the descrip-

tions that follow below.

[`ost] CIP Offset, used exclusively with explicit

messaging where it defines a specific gateway

instance (EZ_ZONE PM or RM controller) to

receive a message originating from the net-

work Master. The CIP offset is unique to each

gateway instance and is added to the pub-

lished instance of any given parameter.

As an example, when programming an explicit mes-

sage ensure that the class, instance and attribute is

defined. To read the first instance of the Process Vari-

able in PM2 use the following information in the mes-

sage instruction:

Class = 104 or (0x68)

Instance = 1

Attribute = 1

Note that the instance is identified as instance 1 be-

cause there is no offset to add. RUI prompt entry for

gateway instance 1 follows:

[`oSt] = 0

RUI prompt entry for gateway instance 2 (PM2) fol-

lows:

[`oSt] = 4

RUI prompt entry for gateway instance 3 follows:

`oSt] = 8

RUI prompt entry for gateway instance 4 follows:

[`oSt] = 12

To read the process value instance 2 of PM4 add

the offset to the instance. The following information

would need to be entered in the message instruction:

Class = 104 or (0x68)

Instance = 14 or (0x0E)

Attribute = 1

[ao;nb] From the gateway perspective, this assembly

represents data that comes from Standard

Bus controllers (EZ-ZONE PM or RM) and

is sent out on the network. As seen from the

network, this is the CIP Implicit Output As-

sembly representing inputs to the Master

and is used exclusively when communicat-

ing implicitly. For any given RUI gateway

instance (EZ-ZONE controller), the output

assembly size will never be greater than 20,

32-bit members. The user entry ranges from

0 to 20.
