Multi unit output signals – FEC AFC1500 User Manual

Multi Unit Output Signals
The Multi Unit is capable of providing over 570 Output signals to indicate the
status of the Multi Unit and all of the AFC1500 SAN Servo Controllers
connected to it (up to 31 controllers). By using the AFC User Console
Software, it is possible to select the signals to be output and set them in a
specific address location. The output layout must be programmed and in
effect there is no assigned outputs. However, FEC sets output signals in a
typical layout but keep in mind that every application could be different.
Refer to the specific applications Electrical Controls drawings for the exact
layout.
When working with the Discrete I/O interface, additional output signals
required beyond 32 outputs are realized using the “BANK” select function.
Up to 8 banks of 32 outputs can be selected, each programmable from the
User Console Software. If the Interface is for a Fieldbus application, Bank
selecting is not necessary. All outputs required can be programmed to specific
fieldbus addresses.
Bank Select Procedure
When using a discrete I/O interface, the output signals can be arrayed in
groups called data “banks” which are selected by the Data Select input signals.
The Data Select signals 0, 1 & 2 form together a binary code to select up to
eight (8) different Data Banks of 32 outputs as shown below;
