Example 2
Assembly objects 104d/154d (separated mode) are used in the example. The following
functions are activated:
■
Set tag type IPC03 on channel 1 and channel 2.
■
Write data to a IPC03 tag.
■
Read data from a IPC03 tag.
Prerequisites:
■
One type IPH-XX read/write head is connected to channel 1 and channel 2 on the
IDENTControl Compact.
■
One type IPC03 tag is located in front of each read/write head.
■
The IP address of the IDENTControl is set to a free address.
■
The device is connected to the network.
Setting connection parameters
These parameters are configured on the PLC:
Division of the input and output instance from the assembly object:
Output instance 104d - 32 bytes
Input instance 154d - 32 bytes
The IDENTControl Compact requires 32 bytes of input data and sends back 32 bytes of output
data.
