3.10. Assigning variables for SOE

The SOE collector provides the user with two options. The user may tag changes for a Boolean

variable which only has two states. However, the collector will also allow the user to add “Channel

state” changes. These channel state changes are described in the ANALOGUE SOE VARIABLES

paragraph.

Note: All SOE variables must either be defined as INPUT or OUTPUT. Intermediate application

variables can be assigned for SOE collection using the SOE board, if they are configured as

outputs in the dictionary as below.

3.10.1. Boolean SOE Variables

To select Boolean variables for collection by the SOE, the user must first open the Data Dictionary

within the IEC1131 TOOLSET, then select the variable to be included in the SOE log. This will initiate

the dialogue box shown in Figure 7.

Figure 7 Boolean Variable Setup

With the above dialogue box open, the user must name the variable by entering the appropriate data in

the Name: window. If the variable is, for example, a field device driven by an output from the System,

the user must enable the O

utput option, then select the Extended button. This will initiate the

dialogue box shown in Figure 8.
