Chapter 3 System Construction
3.6 Startup Procedure
There are the following two modes for I/O module input/output operations:
(1) FL654A recognizes the I/O module composition when the power supply is turned on, and
FL654A executes the input/output operation by this module composition. (AUTO)
3
(2) After confirming the I/O module composition when the power supply is turned on, the user
saves the I/O module composition in non-volatile memory in FL654A. FL654A executes the
input/output operation according to the saved I/O module composition. (CONF/LOCK)
In the mode in (1), if any I/O module is defective at power-ON, I/O module configuration information
is created excluding such I/O module. Thus there is a possibility of disagreement in correspondence
between the common memory and the slots into which I/O modules have been installed. It is
recommended that I/O module input/output be performed on the basis of the information saved in
the non-volatile memory, i.e., in the mode in (2).
3.6.1 CONF/LOCK Designation Startup
(i) Install the power, expansion, FL654A, and I/O
modules in the base unit. When the expansion unit
is used, connect an expansion cable.
(ii) Turn ON the power (the FL654A automatically
recognizes the connected I/O modules).
(iii) Connect a PC to the TOOL connection port
and check I/O module connections using terminal
software.
(iv) After checking I/O module connections, once
turn OFF the power and return the FL654A switch
settings to ordinary usage condition.
(v) Connect the communication cable.
(vi) Turn ON the power.
