Basic 6250 Features

Daisy-Chaining and RP240s

RP240s cannot be placed in the 6250 daisy chain; RP240s can only be connected to the

designated RP240 port on a 6250. It is possible to use only one RP240 with a 6250 daisy-

chain to input data for multiple units on the chain. The example below (for the 6250 master

with an RP240 connected) reads data from the RP240 into variables #1 (data1) & #2 (data2),

then sends the messages 3_Ddata1,data2<CR> and 3_GO<CR>.
