code
3050H System bus error • Communication with the module failed
due to power discontinuity or the like.
3052H System bus error • The initial setting of the high-speed pulse
input/output module caused an error.
3054H System bus error • All module reset is executed.
• The positioning with the high-speed
pulse input/output module caused an
abnormal stop.
3055H System bus error • All module reset is executed.
• The positioning with the high-speed
pulse input/output module caused an
abnormal stop.
3056H System bus error • A timeout occurred during
communication with a connected module
when an instruction was executed.
Action
• Verify that the connected module is powered
on.
• Verify that extension cables are correctly
connected.
• Verify that the version of the CPU module is
compatible with the module where the error
was detected.
• Implement anti-noise measures.
• If there is no problem, there may be a
malfunction in the connected module or in
the extension cables.
• Verify that extension cables are correctly
connected.
• Verify that the version of the CPU module is
compatible with the module where the error
was detected.
• Implement anti-noise measures.
• If there is no problem, there may be a
malfunction in the connected module or in
the extension cables.
• Review the program and check the contents
of the operands used in the applied
instructions.
• Verify that the connected module is powered
on.
• Verify that extension cables are correctly
connected.
• Verify that the version of the CPU module is
compatible with the module where the error
was detected.
• Implement anti-noise measures.
• If there is no problem, there may be a
malfunction in the connected module or in
the extension cables.
• Review the program and check the contents
of the operands used in the applied

connected.
• Verify that the version of the CPU module is
compatible with the module where the error
was detected.
• Implement anti-noise measures.
• If there is no problem, there may be a
malfunction in the connected module or in
the extension cables.
• When an error occurs alongside positioning
function, positioning may not stop at the
specified position. After removing the cause
of the system bus error, perform zero return
and clear error.
