Registering And Assigning Network Variables - Toshiba nv Series User Manual

C.3 Registering and Assigning Network Variables
Assign the controller interface DPRAM data of the PF611A and PF612A module to system
network variables. This enables the user program on the type1 light controller to handle the
cyclic data communicated by cyclic transmission on the PROFIBUS-DP as network
variables. In addition, the data transfer between the module DPRAM and network variable
is performed collectively by the type1 light controller OS at the beginning of the sequence.
The case for PF611A is described below. Set PF612A in the same manner.
(Note that PF611A and PF612A have different memory maps.)
Transmission Block Registration
Register the area used in DPRAM (such as "write data", and "read data", and "RAS
information") as transmission blocks.
"Module control information" is not a data that is constantly updated. Do not register as
transmission block. When necessary, write each time with a write instruction.
(15) Select the "01 (ProfibusLAN)" folder, select [Talker Blocks] at the bottom right of the
screen, and then open the transmission block edit screen by selecting [File (F)] -
[Talker Block]. (The same edit screen can be opened by double-clicking [Talker
Blocks].)
(16) Register the area accessed in the controller interface DPRAM of PF611A as
transmission block. Register the area written from the type1 light controller as
transmission block of PF611ATEST, and the area read as transmission block of
PF612ADMY.
Note1: The [Trans. Speed] for ProfibusLAN is kept at [middle].
Note2: The address in the controller interface DPRAM memory map table (Table B-1, Table
B-2) is used for the word No. in the edit screen. (However, note that the address in the
table is in hexadecimal whereas the address on the edit screen is in decimal.)
