  • Page 2 SAFETY PRECAUTIONS (Read these precautions before using this product.) Before using this product, please read this manual and the relevant manuals carefully and pay full attention to safety to handle the product correctly. In this manual, the safety precautions are classified into two levels: "...
  • Page 3 [INSTALLATION PRECAUTIONS] CAUTION Use the programmable controller in an environment that meets the specifications in the user's manual of the CPU module used. Failure to do so may result in electric shock, fire, malfunction, or damage to or deterioration of the product. Insert the tabs at the bottom of the module into the holes in the base unit before mounting the module.
  • Page 4 [WIRING PRECAUTIONS] CAUTION Tighten the terminal screws within the specified torque range. Undertightening can cause short circuit, fire, or malfunction. Overtightening can damage the screw and/or module, resulting in drop, short circuit, or malfunction. Prevent foreign matter such as dust or wire chips from entering the module. Such foreign matter can cause a fire, failure, or malfunction.
  • Page 5 [STARTUP AND MAINTENANCE PRECAUTIONS] WARNING Do not touch any terminal while power is on. Doing so can cause electric shock. Shut off the external power supply for the system in all phases before cleaning the module or retightening the terminal screws or module fixing screws.
  • Page 6 CONDITIONS OF USE FOR THE PRODUCT (1) Mitsubishi programmable controller ("the PRODUCT") shall be used in conditions; i) where any problem, fault or failure occurring in the PRODUCT, if any, shall not lead to any major or serious accident; and ii) where the backup and fail-safe function are systematically or automatically provided outside of the PRODUCT for the case of any problem, fault or failure occurring in the PRODUCT.

    1. Overview This manual describes the specifications, name of each part, settings, etc., of the AJ61BT11 CC-Link System Master/Local Module (hereafter abbreviated as AJ61BT11) and A1SJ61BT11 CC-Link System Master/ Local Module (hereafter abbreviated as A1SJ61BT11) to be used in combination with the MELSEC-A series programmable controller CPU.
  • Page 12: Performance Specification

    2. Performance Specification 2.1 Performance specification The following shows the performance specification of the AJ61BT11 and A1SJ61BT11. Refer to the CPU module User's Manual to be used for general specification of AJ61BT11 and A1SJ61BT11. Item Specification Transmission speed Selectable from 156kbps/625kbps/2.5Mbps/5Mbps/10Mbps...
  • Page 13 Weight AJ61BT11:0.4kg , A1SJ61BT11:0.25kg This setting is applicable to the AJ61BT11 of hardware version F or later and the A1SJ61BT11 of hardware version G or later. For the modules with other versions, the setting is "1 station" and "4 stations" only.
  • Page 14: Maximum Overall Cable Distance

    2.1.1 Maximum overall cable distance The maximum overall cable distance differs according to the transmission speed. For the relationship between the transmission speed and maximum overall cable distance, refer to the CC-Link System Master/Local Module User's Manual. 2.2 CC-Link dedicated cable Use the CC-Link dedicated cables in a CC-Link system.
  • Page 15: Name And Setting Of Each Component

    3. Name and Setting of Each Component This section explains the name and setting of each component of AJ61BT11 and A1SJ61BT11.
  • Page 16 Name Description LED display Data link status can be checked from the LED on status. LED name Description ON : Module is normal. OFF: Watchdog timer error. Communication error at all stations. ERR. Flashing: Communication faulty station exists. Set as a master station. S MST Set as a standby master station.
  • Page 17 Name Description Station number setting switch Set the module station number.(setting at shipment: 0) AJ61BT11 <Range> STATION NO. • In the remote net mode Master station: 0 Local station: 1 to 64 Standby master station: 1 to 63 The "SW" and "L ERR." LEDs are turned on when a value other than 0 to 64 is set.
  • Page 18 (FG) (Replace the module after turning off its power.) The AJ61BT11 of hardware version F or later and the A1SJ61BT11 of hardware version G or later are compatible with this setting. For other than the above, only SW5 is used to set the number of occupied stations.
  • Page 19 Point The setting for the switches (2) to (5) when the module power supply is turned OFF  ON is valid. When the setting is changed while the module power supply is on, reset the programmable controller CPU or turn off and then on the module power supply again. Important Do not use station number 64 in a system where the waiting master station exists.
  • Page 20: Loading And Installation

    The following is explanations of the handling precautions and installation environment, which is common to modules when handling AJ61BT11 and A1SJ61BT11 from unpacking to installation.
