Chapter 1 Series 1700 Introduction
Module Setup Parameters (continued)
Single Transfer Length
The Single Transfer Length parameter is a new parameter used to specify either a 16 or 32
bit transfer. This parameter is only available if you have selected single transfers with the
Transfer Type parameter. If you selected block transfers, the PLC Program parameter is shown
instead.
hý The Single Transfer Length default is 16 bit. This allows the transfer of position data
only. Setting the parameter to 32 bit allows the transfer of both the position and
tachometer data.
hý The Single Transfer Length parameter is only programmable from the keyboard.
-08 option
Prior to hardware revision H, customers could order modules with 32 bit single transfer by
adding "-08" to the end of the part number. This practice has been eliminated because 32 bit
single transfer is now standard on the modules. If your module is a replacement for an older
"-08" module, it will work correctly if the Transfer Type parameter is set to single and the
Single Transfer Length parameter is set to 32 bit.
Resolver Type
The Resolver Type parameter is a new parameter that makes most Autotech transducers
compatible with the Series 1700 modules.
hý The Resolver Type default value is AMCI, resolver 1. If you are using Autotech
transducers, set this parameter to resolver 2.
hý
The Resolver Type parameter is only programmable from the keyboard.

1) If the Single Transfer Length parameter is set to 16 bit, the chassis can be
configured for 2-slot, 1-slot, or ½-slot addressing. If the parameter is set to
32 bit, you must use 1-slot or ½-slot addressing.
2) After changing this parameter, you must cycle power to the module to re-
initialize the A-B backplane interface chip.
If you plan to use both AMCI and Autotech resolvers with a single module you
must set the Resolver Type to AMCI, resolver 1. You will need an RM-3
Reference Module to interface the Autotech transducers with the card.
