4.4.12. Map Descriptor Example 9 - read initial setpoint channel

// Client Side Map Descriptors

Map Descriptors

Map_Descriptor_Name, Scan_Interval, Data_Array_Name, Data_Array_Offset, Function,

Node_Name, SysPlus_Data_Type, Address, Length

Init_Setpoint_00, 0s, Init_Setpoint, 0, rdbc, SYSPLUS_01, Init_Setpoint, 0, 1

The channel is specified by the “Address” field.

4.4.13. Map Descriptor Example 10 - set initial setpoint channel = value

// Client Side Map Descriptors

Map Descriptors

Map_Descriptor_Name, Data_Array_Name, Data_Array_Offset, Function,

Node_Name, SysPlus_Data_Type, Address, Length

Init_Setpoint_00, Init_Setpoint_0, 0, awt, SYSPLUS_01, Init_Setpoint, 0, 1

The channel is specified by the “Address” field; value is retrieved from the value written into Data_Array_Name at Data_Array_Offset.

4.4.14. Map Descriptor Example 11 - read program status

// Client Side Map Descriptors

Map Descriptor

Map_Descriptor_Name, Scan_Interval, Data_Array_Name, Data_Array_Offset, Function,

Node_Name, SysPlus_Data_Type, Length

Prg_Sts, 0s, Prog_Status, 0, rdbc, SYSPLUS_01, Prog_Status, 1

The program status will be stored to Data_Array_Name at Data_Array_Offset with one of the following possible values:

Program Status VALUE

Undefined

Timed Start 1

Alarm Hold 2

Hold 3

Run 4

Timed Stop 5

Stop 6
