6 ． EtherNet/IP Settings 6.3. Allocating the Tag Data Links The data in the tag data links of the Destination Device is allocated to the global variables of the Controller. The relationship between the destination device data and the global variables is shown below. The following global variables are set in the "Configuration Files". ■ Output area (from Controller to FZ5 Sensor Controller) *1: Details on allocation of control signal Allocation of ControlFlag.F Offset +0 +1 EXE: Command Request Bit: Turned ON to execute a command. STEP: Measure Bit: Turned ON to execute a measurement. XEXE: Flow Command Request Bit:
Turned ON to request execution of a command during execution of fieldbus flow control. ERCLR: Error Clear Bit: Turned ON to clear the Error Status bit. DSA: Data Output Request Bit: Turned ON to request data output. Allocation of ControlFlag.W. Offset +0 +1 Bits 31 to 0: ControlFlag.W uses DWORD data from the offset +0 word. 9 Variable Data type Data size EIP002 OUT _ S EIPOutput _ 20 bytes Offset Destination device data Global variable Data type +0 to +1 Control signal (32 bits) (Data type:
