NOTE: The PLC will receive both words with each discrete read, but it is not guaranteed that
both words will be transferred as a unit. Both words will get transferred, but there
may be some delay between the two.
NOTE: For the PLC-2
®
series, you must use a 1772-SD2 scanner and the PLC-2
®
system to
allow communication with the HI 2151WC via block transfer. Use block transfers
only.
NOTE: For the SLC 5/02
®
or above processors, you must use a 1747-SN to allow communi-
cation with the HI 2151WC via discrete transfer. The 1747-SN does not support block
transfer.
