horner xle with misubishi fx2n-64 plc

Hello, Has anybody used a horner xl units to contol Mitsubishi fx plc's (cscape with fx protocol)? My problem is mapping single bit registers from the fx (x,y,&M relays) to the cscape registers (16 bit registers). The help file says single bit registers are sent to cscape in packs of 16. Does this mean, if I map Y0 (1bit)from the fx to %R001 (16bit) on the xle , that y0 acually maps to %R001.1 and y1 would map to %R001.2, and so on?
Thank,s

I assume that you have gotten comms going, etc.
Horner maps registers (populates I should say) starting at bit 1.
Therefore your Y0 will map to register %R001.1, Y1 to %R001.2, and so on.
Your last bit which should be Y15 maps to %R001.16
