Each Write Word 12 specifies the time in hundredths of a second the FIP Bus Controller will wait for a write transfer to complete before setting the Channel Error bit and Detailed Channel Status bits to indicate a non fatal timeout error The transfer can still complete even after a timeout occurs As a result an application can choose what to do if one occurs If the timeout value is specified as zero no timeout errors will be reported For most applications a timeout need not be specified because the write period in effect acts as a timeout Word 12 should be zero for no timeout However there are two special circumstances in which specifying a timeout is recommended A When the number of time units word 11 is zero so that a subsequent transfer will be issued as soon as the previous transfer completes and no period errors are reported In this case a timeout value can be specified so that timeout errors will be reported by the Channel Error bit B When the write period is very long minutes or hours In this case a shorter timeout value can be specified so the application doesn t have to wait for the write period to expire before taking action Word 13 Local PLC Memory Type Words 13 14 specify the location in the local PLC from where the FIP Bus Controller will get the data to be written to the remote PLC The size of this area is set by the size of the data written to the remote PLC Valid memory types are
