(4) Precautions for basic parameter setting
(a) When setting the basic parameters with a sequence program, set the basic
parameter starting method (b0) of the intelligent function module switch 2
(refer to Section 6.6) to ON (Start with the user-set parameters).
(b) Turn ON Basic parameter setting request (Y1) after Module READY (X0)
has turned ON.
(c) After Basic parameter setting request (Y1) is turned ON to start the
parameter setting processing, do not turn ON/OFF any other output signal
(Y signal) until Basic parameter setting, normally completed (X1) or Basic
parameter setting, error completed (X2) turns ON.
(d) When the basic parameter setting is completed with an error, an error code
is stored into the basic parameter error code storage area (address: C10
H
(3088)) of the buffer memory.
Check the stored error code, take corrective action, and make a parameter
setting request again. Refer to Section 11.3 for details of the error code.
(e) Basic parameter setting existence (X3) turns ON when the default
parameters exist.
(f) The basic parameter setting is not allowed in the offline mode (intelligent
function module switch 1: 0001
H
).
Set the basic parameters in the online mode (intelligent function module
switch 1: 0000
H
).
REMARK
Refer to Section 6.6.1 for details of whether each function can be executed or not
depending on the basic parameter setting existence.
