16 Inputs a re level or edge triggered and can be user

c o n f i g u red as limit, home, stop, erro r, or general

purpose inputs. General purpose inputs may be

c o n f i g u red to interrupt the MINT™ or C program and

call a service ro u t i n e .

8 Outputs a re user configured as drive enable, erro r

output or general purpose outputs. All user outputs

a re over current protected and a fault condition will

generate and ERROR to the MINT or C pro g r a m .

Analog Inputs can be read as 8 x 12 bit values

(single ended input) or 4 x 12 bit values, (diff e re n t i a l

i n p u t ) .

Remote I/O is connected to the CANbus port and is

simply read from, and written to, using MINT or ‘C’

f u n c t i o n s .

R S 2 3 2 port supports the industry standard full duplex

ASCII protocol. This allows easy connection to almost

any device with a serial port.

RS485 port allows up to 16 NextMove BX contro l l e r s

to be linked together on a single RS485 multi-dro p .

COMMS Array p rovide an efficient way to transfer

data bidirectionally between a MINT program running

on NextMove BX and a separate user pro g r a m

running on the host contro l l e r. COMMS array gives the

serial port the same functionality as a parallel dual port

r a m .

C A N b u s is used to communicate to Baldor’s re m o t e

I/O blocks and operator keypad.

P rogramming Options

MINT is the easiest and quickest way to program the

NextMove BX contro l l e r. MINT programs are

developed using the MINT Programmers toolkit which

is supplied as standard with every NextMove product.

‘C’ Function Libraries’. P rograms written in 'C' will

typically run faster than MINT programs but they

re q u i re a good working knowledge of 'C'. 'C' code

must be complied to run on the TMS320C31 pro c e s-

sor inside the NextMove BX. 'C' does not support

interrupts on inputs. The 'C' functions are contained in

B a l d o r ’s MINT Interface Library CD product, and the

TMS320C31 cross complier is available from Te x a s
