    Parameters Figure 1.1 Logical Structure of Each Block Node address, block tags and contained parameters within a function block are structured in the FLXA21 device as shown in figure 1.1. 1.3 Wiring System Configuration The number of devices that can be connected to a single bus and the cable length vary depending on system design. When constructing systems, both the basic and overall design must be carefully considered to allow device performance to be fully exhibited.

    Using the host device display function, check that the FLXA21 is in operation on the bus. Unless otherwise specified, the following settings are in effect when shipped from the factory. If no FLXA21 is detected, check the available address. Please set all addresses of the devices in advance or separately connect each FLXA21 and set a different address for each. Make sure to note the address after changing it as from this point on the device can only be accessed through this address.

  • Page 16: Notes When Using The Flxa21-Sc Concentration Table (When Using Fieldmate)

    <3. Getting Started> Notes When Using the FLXA21-SC Concentration Table (when using FieldMate) The FLXA21-SC concentration table can be read from and written to using the CONC_TABLE_ CONCENTRATION_1 to CONC_TABLE_CONCENTRATION_21 and CONC_TABLE_ CONDUCTIVITY_1 to CONC_TABLE_CONDUCTIVITY_21 parameters of the transducer block. However, when using FieldMate, note the following points. The default concentration table values are “Not a Number”. On the device screen, they appear as blank. On FieldMate, “IEEE: NOT A NUMBER” is displayed. Values set to “Not a Number” cannot be changed from FieldMate. If you want to write the concentration table from FieldMate, first set all the items in the concentration table to some value from the device screen. PRIMARY/SECONDARY/TERTIARY/ QUATERNARY_VALUE Value Assignment Measurement values are assigned to PRIMARY_VALUE, SECONDARY_VALUE, TERTIARY_ VALUE, and QUATERNARY_VALUE from the device screen.

  • Page 17: Explanation Of Basic Item

    In general, slave devices exchange data cyclically with the master (class 1, e.g. PLC). The FLXA21 (slave) gets the data from the sensor, makes some calculations and makes the outcome available through analog input blocks. The controller device (Master) requests for these process values, makes some calculation (PID, ratio) and sends the result to an actuator.

  • Page 18: Reading Acyclic Parameters

    <4. Explanation of Basic Item> The AI1/2 measurement items assigned to each slot are determined according to Channel (AI) as well as PRIMARY, SECONDARY, TERTIARY, and QUATERNARY Type (Transducer Block). For details, see the description of each item. The GSD file of the FLXA21 specifies 3 modules: ;Empty module Module = “Empty Module” 0x00 EndModule ;Modules for Analog Input Module = “Analog Input (AI)short”...

  • Page 19: Function Block Parameters

    The actual mode is changed by setting the target mode. When the physical block mode is set to OOS all function blocks are set to OOS mode. CHANNEL Channel is the parameter to select the signal which is calculated in SENSOR Transducer Block. The values are assigned to channels. For the FLXA21 three or four channels are available. For the FLXA21, you can select from the PRIMARY, SECONDARY, TERTIARY, QUATENARY values assigned to the Transducer Block. For details on how to assign measurement items to parameters, refer to “3.6 PRIMARY/ SECONDARY/TERTIARY/QUATERNARY_VALUE Value Assignment”.
