• Values for CH, UNIT, and SLOT are entered using the variables (CH, UNIT,
SLOT) set by an initialize request.
• After slave parameter setting request processing is completed, the end con-
firmation coil END_SLAVESET turns TRUE.
(d) Operation mode control request
• When a slave node parameter setting request is completed,
END_SLAVESET becomes TRUE, turning the start relay MODESET for the
operation mode control setting request TRUE and starting operation.
• Values for CH, UNIT, and SLOT are entered using the variables (CH, UNIT,
SLOT) set by an initialize request. [16#1210] is entered for SPEC to set run
request, polling transmission enable, transmission start, and asynchronous
mode.
• When an operation mode control request is completed, the end confirmation
coil END_MODESET becomes TRUE,
(e) Slave data input/output
• When an operation mode control request is completed, END_MODESET
becomes TRUE, turning the start relay ASWRITE for slave data output TRUE
and starting operation.
• Values for CH, UNIT, and SLOT are entered using the variables (CH, UNIT,
SLOT) set by an initialize request. A read/write node address is entered for
NODE. 0 is entered for BS in polling mode, or 1 BS in bit strobe mode.
• The output address to the slave device DO used here is the first of the two
words. so if data is written in the first word (ASWRITE_DT.WDT[0]) of the
slave data output structure ASWRITE_DT, it is output to the slave device of a
specified address.
• When output data write is completed, the end confirmation coil
END_ASWRITE becomes TRUE, turning the start relay ASREAD for slave
data input TRUE and starting operation.
