Appendix A:
CIP POSITION SENSOR OBJECT
Common Industrial Protocol
DeviceNet is a protocol stack that implements the Common Industrial Protocol (CIP) over CANbus . The CIP is sponsored by
the Open DeviceNet Vendors Association (ODVA) and is implemented over a variety of networks . The RM-89 follows the
Resolver Device Profile that is defined in the CIP specification . The explicit messages described in chapter 5 are custom
instances that simplify configuring and programming the resolver when using explicit messaging .
In addition to these custom instances, the RM-89 implements the Position Sensor Object, which is a mandatory object for
every product that implements the Resolver Device Profile as defined in the specification . The explicit messages that are used
to preset the position value and save the programmed parameters are two commands defined in the Position Sensor Object .
The RM-89 implements the CIP revision 2 definition of the Position Sensor Object .
Note:
Using the Position Sensor Object to communicate with the RM-89 is
completely optional.
Most applications should
communicate with the RM-89 using the custom instances as explained in the previous two chapters because it will greatly
simplify your PLC programming . The only reasons to use the Position Sensor Object is if you need extremely fine grain
control over communications with the RM-89 or if you use DeviceNet resolvers from multiple vendors and you decide to
write code that can be used with any of these sensors .
Supported Services
The following table lists the common services implemented by the RM-89 for the Position Sensor Object
The services that are implemented only on the Class level (not on the Instance) should address Instance 0 .
•Service Code 16#0E,
Get_Attribute_Single
is used to read data from the Position Sensor Object class .
•Service Code 16#10,
Set_Attribute_Single
is used to write data to the Position Sensor Object class .
