MAPPING Statement mapped to a V+ signal. The /BIT_LENGTH parameter defines how many bits to map to V+ signal numbers. In the MAPPING 1 statement the parameter /BIT_LENGTH has the value 1. This means that exactly one bit is mapped to one signal, starting with the signal number given in the /SIGNAL parameter. 4. The /SIGNAL parameter specifies the starting number of a series of V+ signals. The following example shows the mapping of V+ signals 33, 1033, 1034, and 1035 to digital I/Os on the DeviceNet. l The MAPPING 1 statement maps one digital output on the WAGO I/O block to one digital I/O signal in V+.
l In the MAPPING 2 statement the parameter /BIT_LENGTH has the value 3, which means that three signals, starting with signal 1033, are mapped. Current statements in the DEVICENET section: MAPPING 1 = "/MACID 1 /BYTE 2 /BIT 2 /BIT_LENGTH 1 /SIGNAL 33" MAPPING 2 = "/MACID 1 /BYTE 2 /BIT 2 /BIT_LENGTH 3 /SIGNAL 1033" The information about how many bytes V+ reads from the DeviceNet bus and how many it writes is spe- cified in the MACID statement. These values are typically found while scanning the DeviceNet bus with the DeviceNet scanner. For more information on DeviceNet, see the DeviceNet topic in the V+ Language User's Guide .
