SYSTEM CONFIGURATION
2.4 System Configuration Cautions
(1) Extension base unit
The extension base unit cannot be connected to the main base unit where the
Redundant CPU whose first 5 digits of serial No. is "09011" or earlier is mounted.
If connected, a stop error "BASE LAY ERROR (error code: 2010)" occurs.
When connecting the extension base unit, there are following restrictions.
• Use Redundant CPUs whose first 5 digits of serial No. are "09012" or later for
both systems.
• Connnect a redundant type extension base unit as the first extension stage. As
the second and later stages, redundant power extension base units only can be
used.
• Only one redundant type extension base unit can be used per system.
• Connect IN connector (IN1 and IN2) of the redundant type extension base unit to
OUT connector of the main base unit.
• Connect OUT connector of the redundant type extension base unit to IN
connector of the redundant power extension base unit.
• Use the same main base unit models in systems A and B.
• Configuration of multiple CPU system is not allowed.
• Do not power OFF or reset the control system in Separate mode.
• Do not perform boot operation of a Redundant CPU whose first 5 digits of serial
No. is "09011" or earlier, using a memory card storing network parameters for
Ethernet and CC-Link configurations on an extension base unit.
• Do not disconnect the extension cable while the power supply module mounted
on the main base unit is ON.
• Any dedicated instructions cannot be used to intelligent function modules on
extension base units. ( Section 7.1 (8))
• Any interrupt pointer caused by an interrupt from an intelligent function module
on an extension base unit cannot be used. ( Section 7.5 (4))
• Connect extension cables so that an overall cable distance
*1
does not exceed
13.2 m (43.31 feet).
* 1: To calculate an overall cable distance, use the longer length for the two extension cables
connecting between the system A or B main base unit and the redundant type extension base unit
System A
System B
System A extension cable:
1.5 m(4.92 feet)
Example) System A extension cable...1.5 m(4.92 feet)
System B extension cable...3 m(9.84 feet)
Extension cable: 2 m(6.56 feet)
Extension cable: 5 m(16.40 feet)
System B extension cable: 3 m(9.84 feet)
3+2+5=10 m(32.81 feet) 13.2 m(43.31 feet)
