Does the AN-X(2)-AB-DHRIO gateway running the RIO HMI firmware support multiple block transfers to the same Rack, Group, and Slot?

Yes it can support HMI applications where multiple BTRs and/or BTWs are mapped to the same Rack, Group, and Slot number. To configure the gateway to accept multiple BTRs or BTWs to the same Rack, Group, and Slot Number, it is necessary to add the BtByLen keyword into the configuration file as follows:

RioCfg,  ; start of configuration

Baud,115k2,  ;define baud rate for 1771 IO network (57k6,115k2,230k4)

Rack,0o02,1,4 ; define rack at octal 02, start quarter 1, and quarter 4

; Allows multiple BTRs and BTWs to occur to the same Rack, Group, and Slot.
BtByLen

btW,0o02,0,0,7, 0,64, ; define btw, rack 02, group 0, slot 0 ;-> N7:0 , length is 64
btW,0o02,0,0,7,64,63, ; define btw, rack 02, group 0, slot 0 ;-> N7:64, length is 63

EndRioCfg

Note: When BtByLen is declared, only a single Remote I/O rack can be used.
