USER'S GUIDE MOTION CONTROL SYSTEM, MSC-250
1 - 14 DESCRIPTION MARCH 2003
2. AXIS STATUS Displays: One 7-segment LED with decimal place indicates
the status for each of the axes. Each number
displayed represents a specific status code. (Refer
to "Section 3.2 - Controller Use and Status" for the
meaning of these codes.) An illuminated decimal
point indicates that the drive for that axis is enabled.
3. On-board I/O Status Indicators: There is one LED position for each of the 16
on-board I/O locations. When the I/O module
is accessed, an LED will illuminate beneath the
number of the I/O location. If no module is
present, the illumination will be dim. If the
module is present, the illumination will be
bright.
1.3.2 CONNECTORS
1. PROM POCKET: This 28-pin ZIF (Zero Insertion Force) socket accepts
PROMs for program input and data storage.
2. PORT 1: This 25-pin serial communications port can use either an
RS-232C serial communications protocol or an RS-485
multidrop addressable protocol. It is used for
communications with the computer using the MSC Tool Kit
program. The ADDRESS switch on the printed circuit board
must be set to allow proper communications. (Refer to
"Section 2 - Installation" for proper cable pin-outs for this
port.)
3. PORT 2: This 20 mA current-loop serial port is used for
communication with the Industrial Indexing Systems' OPI-1
and similar current-loop communications devices. It is
accessible through the Macroprogram language for sending
and receiving data and commands. (Refer to "Section 2 -
Installation" for proper cable pin-outs for this port.)
NOTE
An RS-232C to 20 mA converter is available from Industrial Indexing
Systems, Inc. This converter allows the user to take advantage of
the high-isolation characteristics of the 20 mA current-loop
communications protocol.
