5 USER GUIDE
5-54
After a request is issued by the C mode handler, do not make another message request until
the “user request processing in progress” bit is reset. If any message request is issued
before the bit is reset, it is not processed because another message is being processed (the
“message processing already in progress” error code is set at an error code storage address).
After the “user request processing in progress” bit is reset, enter the status prevailing after
the end of the processing at an error code storage address specified at C mode handler
startup.
To check whether the requested processing is ended normally, note the code that is set at the
error code storage address.

Note: For bit allocation for the self-node status flag, see “5.4.6 Using the management tables.”
Do not mix to use C mode handler and mathematical/logical function.
Please be sure to unify either C mode handler or mathematical/logical function
at FL.NET module unit.
When mounting S10V, FL.NET module (LQE500) before Module Rev.B (Ver-
Rev: 0002-0000) doesn’t provide for message communication function (neither
do C mode handler and mathematical/logical function), but provided for cyclic
communication function having applied common memory area. Utilizing
message communication function in combination with S10V, you should use
the module after Module Rev.C (Ver-Rev: 0003-0000).
Moreover, the above-mentioned Ver-Rev is a micro program Ver-Rev of
FL.NET module which is shown on “Module List” of S10V BASE SYSTEM.
