TB197 Rev1 PLC Firmware Compatability Issues
Purpose
The reason this Tech Bulletin was created was due to the latest release of RTK3 PLCIO2 and DC3IO
firmware It was discovered that it is not compatable with the old versions of IO2PIC firmware on our motion
control cards Symptoms of the incompatability are IO being recognized in the opposite state at power up i e
unclamp spindle fault This document will cover which firmware version on a PLCIO2 RTK3 and DC3IO are
compatible with which CPU cards Refer to TB187 to determine the PIC type on the CPU card This Tech
bulletin refers only to CPU cards with IO2PIC's
Â
CPU Card PLC Type and Firmware
CPU10b Works with all firmware versions for the RTK3 PLCIO2 and DC3IO
CPU7 CPU9 CPU10
IO2PIC 050426 The newest IO2PIC software for the PIC makes these CPUs compatable with
the SXPLCIO2 060301 version of firmware which can be on all three PLC types
CPU 7 CPU9 CPU10
all previous versions Will work with the SXPLCIO2 020819 SXRTK3 030421 or older versions of
firmware Note Any PIC version before 050426 will not work with the DC3IO on
a CPU7 CPU9 or CPU10
