TROUBLESHOOTING
(2) When using the slim type base unit (Q3 SB)
Precautions
• When configuring a multiple CPU system using a slim type main base unit, C
Controller modules only can be used.
• The slim type main base unit has no extension cable connector.
Connection of extension base units and a GOT (in a bus topology) is not
allowed.
• Mounting three or more CPU modules is not allowed since the rating output
current of the power supply module (Q61SP) will exceed the current
consumption of the CPU modules.
