Broadcast Global data is referenced by using the %GL memory type. The offset entered corresponds to the byte offset of the PCIM card. %GL0 is the first offset and refers to BYTE 1, %GL1 is BYTE 2, etc.
Broadcast data may be modified by performing setpoint operations on the points configured for the device. You must ensure that the number of byte being broadcast is compatible with other devices on the network. For example, if the broadcast data is being mapped to the Register memory of a Series 90 Bus Controller, the number of bytes broadcast needs to be on an even-byte boundary.
