1.3 MC300 CONTROL UNIT WITH ENCLOSURE
The MC300 version with aluminium enclosure is a fully enclosed version for bracket mounting
on machine chassis or for use as a hand terminal. It is equpped with RS232/RS422
connections. An adapter module is available for using optical fibre connection.
1.4 MCWAY I/O SYSTEM
McWay i/o system is connected to the MC300 McWay connection to operate as a fast ring
topology serial network with down to 0,5 ms refresh rate.
McWay i/o modules use standard rail mounting and terminal blocks to provide easy panel
assembly.
MC300 is available with either RS-422 or optical fibre McWay and serial interface version. The
RS-422 signal enables use with twisted pair cables whereas the optical fibre provides optimum
EMC performance and fast communications for up to 50m distances. RS-232 is provided for
short distance communication with a PC or other data equipment.
The MC300 hand terminal version with enclosure is equipped with RS-422/232 signals. Optical
fibre communications can be obtained using the WGT02310 transceiver module with it.
The 1,25ms refresh rate means that input information for the control unit and data on the
output modules are never more than 1,25ms old. Thus, it is possible to perform closed loop
servo control with the remote servo axis connection modules.
More details of the operation of McWay modules can be found in the ARLACON McWay i/o
system user's manual.
1.5 MCBASIC PROGRAMMING LANGUAGE
The McBasic is a programming environment developed for use with ARLACON control
systems. It combines the ease of the standard Basic programming language and interpreter
type interactive programming and testing with a fast runtime compiler, multitasking capabilities
and powerful logic and motion control commands.
The McBasic version in MC300 runs under McDOS operating system allowing use of McDOS
file and communication systems and utility programs. By using a WAKEUP.EX start-up batch
file the system can be set to directly start at system power-up and automatically run the
application program if loaded in memory or from some of the available memory devices.
MC300 supports 16 logical axes of which up to 8 can be physical axes controlled by the
system simultaneously. Up to 504 input bits and 504 output bits can be connected via the
McWay I/O system.
With its full floating point mathematics, strings, arrays, functions and structures, McBasic gives
you tools for effective programming of work cycles, interactive user interfaces,
communications and data processing. Up to 32 simultaneous tasks can run in MC300. Tasks
can also be created and killed at any time by the application program.
The McBasic programming language is described in detail in the ARLACON McBasic
programming environment reference manual.
