  • Page 12: Coil

    Ladder Elements Coil The state of the left link is copied to the associated Boolean variable and to the right link. Negated Coil The state of the left link is copied to the right link. The inverse of the state of the left link is copied to the associated Boolean variable, that is, if the state of the left link is OFF, then the state of the associated variable is ON, and vice versa.

Some are Analog Input (DF44), Analog Output (DF46), Temperature input (DF45), Foundation Fieldbus Scanner (FB700) and soon will include DeviceNet and Profibus modules.

  • Page 97: Configuration And Hardware Consistency

    LogicView Configuration and Hardware Consistency It is extremely important that the rack number and the position of each module in the configuration match the actual hardware assembly. Many of the modules on a DF65 system are not intelligent and the CPU cannot know if they are misplaced or non existent. More elaborate modules, like the DF45, will cause warning messages from the FB700, if the actual positioning does not match the software configuration.

  • Page 98: Editing The I/O Modules

    These types of modules give the user an extra degree of flexibility. Typically modules that are related to analog signals, special sensors and those that acquire/send signals using popular protocols such as Modbus, DeviceNet, Profibus and Foundation Fieldbus have a dedicated level of configuration.
  • Page 99 LogicView This number comes in the range from 0 to 10,000. This number has the meaning of percentage with an imaginary fixed point to separate the last 2 decimal digits. For example 5000 represents 50.00 % while 10000 represents 100.00 % of the inputs selected range. Another example is when the input shows as 5460 it is actually indicating 54.60 % of the selected input range.

    LogicView Note for DF45 Module The DF45 Module has an internal configuration. When an existent DF45 module in the original configuration has its configuration changed in the Full Online Edition, DF65 will interrupt the reading of this module from the receipt of the command which has the new configuration. After the control transference for the new configuration, the module can be read again.

    LogicView User Function Blocks Introduction User function blocks (UF) are boolean functions created by the user to simulate combinations of normally closed relays (NC), normally open relays (NO) and coils. To create user functions it is required to have one or more module on the Hardware Page or one or more auxiliary variables in the Virtual Page Table.

We advise that the ENET-700’s baud rate be set as 19200 bps and ENET-710´s baud rate be set as 115200 bps. Connect the CPU and the ENET-700/ ENET-710 through ports P1 or P2 or P3. (As shown below) Certify that the CPU Dip Switch is not in the default position.
  • Page 210 Troubleshooting DF65 does not communicate with DF45 or modules in the racks. Solution: STEP1: Check the key in the racks to be sure it is placed in the same position as displayed in the DF65. The key in the rack is located in the back of the CPU module. Be sure the number there is the same as in the established configuration on the LogicView.
