5 PROGRAMMING
*1 Before the communication program is executed with remote device stations, the
program enclosed by the dotted line 1) enables the initial setting by using the SB0D
(remote device station initialization procedure registration instruction) and SB5F
(completion status of remote device station initialization procedure). Initialization
processing cannot be executed only by setting parameters of GX Developer.
*2 When multiple remote device stations are used, correct the program enclosed by
the dotted line 1) as shown below.
[System configuration]
[Corrected program]
RX(m+1)B and RX(n+1)B are remote READY.
RX(m+1)8 and RX(n+1)8 are initial data processing request flags.
Insert the remote READY and initial data processing request flags for all the
stations, to which the remote device station initialization procedure registration
has been made, into the program as an interlock.
If the following modules are used as remote device stations, configure initial
settings of these stations using a sequence program.
AJ65BT-64AD analog-digital converter module
AJ65BT-68TD thermocouple temperature input module
AJ65BT-64RD3 platinum temperature-measuring resistor Pt100
temperature input module
AJ65BT-64RD4 platinum temperature-measuring resistor Pt100
temperature input module
The above corrected program does not apply to these stations because the
condition where the remote READY turns on differs between the AJ65SBT-64AD
and these remote device stations.
*3 The program enclosed by the dotted line 2) is necessary only when the initial
settings are changed.
