Read CIP Data

There are two ASP functions you can use to read CIP data.

Function: CIPMessage(path, service, class, instance,

attribute, member, data, returntype)

The

CIPMessage function performs the CIP service specified by the

service parameter on an object or object instance specified by the

class, instance, attribute, and member parameters, using the

data passed in the

data parameter (if necessary) and returning the

value with a type specified by the

returntype parameter (if

appropriate).

Parameters:

Example:

For example, a GET_ATTRIBUTE_ALL to the identity object of a

device in slot 1 of the local chassis:

<% CIPMessage("1,1", 1, 1, 1, 0, 0,"","STRING"); %>

This ASP call returns a string similar to:

01 00 0E 00 03 00 0C 0C 70 30 63 2E 08 00 1D 31 37 35

36 2D 4C 31 2F 41 20 31 37 35 36 2D 4D 30 2F 30 20 41

52 47 5F 31 32 5F 33 38

data The data to be passed. If no data is passed in the request, set the data parameter to an

empty string.

returntype The returntype parameter is the same as the tagtype parameter used in the

read-controller-tag functions, except when a returntype of “STRING” is specified, the data

returned from the service is written to the browser as a space-delimited string of

hex digits.
