6.2 Self-definition of Functions (Self-defined)
6.2.1 Explanation of self-definition of functions (self-defined)
The self-definition of functions (self-defined) refers to placement of the communication addresses of data
content that the user needs to read and to write in a system-designated communications block
(H0C00~H1CFF) in accordance with the users needs, and then reading and writing the needed data
content from that communications block (H0B00~H1BFF).
H0C00~H1CFF ↔ H0B00~H1BFF＝ communication address definition block ↔ data content reading
and writing block
Notes: The communication addresses to be read and written must be first placed in the communication address
definition block, which will allow the system to read and to write the data content on the basis of the read
communication addresses.
6.2.2 Settings for Self-definition of Functions (Self-defined)
A. Communication address definition block: First add the communication addresses to be read and
written to [H0C00~H1CFF]
Example: As shown in the figure below, the PV value of input channel 1 of station number 0 is [H0268], the PV
value of input channel 2 of station number 1 is [H1269], and the SV value of input channel 1 of station number 2
is [H2270]; before self-definition of functions, the PC (host computer) must use multiple commands to get the
desired data. Users can in advance arrange to write [H0268] to [H0C00], write [H1269] to [H0C01], and write
[H2270] to [H0C02] to use a single command to get these data late.
B. Read/write data content: In accordance with the foregoing communication addresses [H0C00~H1CFF]
and the corresponding communications areas [H0B00~H1BFF], read and write the data content of the
already-established communication addresses
Example: As in the example above, when the communication addresses have been written to [H0C00, H0C01,
H0C02], find the corresponding communication addresses [H0B00, H0B01, H0B02], then you can use a single
command to read and write the required data content at one time.
