The example program below is explained on the following pages. We present the program here (and on the next page)
in its entirety for your reference. Note – Block transfer is only required when using the 1771–SN sub I/Oscanner
Block transfers allow communications between the sub–scanner and PLC. Block transfers are not required for any
other type of scanner module.
