18. NDTR TMR and OFDTR are used in program blocks that are NOT called every sweep The timers accumulate time across calls to the sub block unless they are reset This means that they function like timers operating in a program with a much slower sweep than the timers in the main program block For program blocks that are inactive for large periods of time the timers should be programmed in such a manner as to account for this catch up feature Related to this are timers that are skipped because of the use of the JUMP instruction Timers that are skipped will NOT catch up and will therefore not accumulate time in the same manner as if they were executed every sweep Constant sweep Constant Sweep time when used should be set at least 10 milliseconds greater than the normal sweep time to avoid any over sweep conditions when monitoring or performing on line changes with the programmer Window completion faults will occur if the constant sweep setting is not high enough A consistent over sweep condition can cause the programmer to lose communications with the PLC Large number of COMMREQs sent to A large number of COMMREQs typically greater than eight sent to a module in one sweep causes faults given board in the same sweep may cause Module Software faults to be logged in the Controller fault table The fault group is MOD_OTHR_SOFTWR 16t 10h and the error code is COMMREQ_MB_FULL_START 2 When this occurs the FT output of the function
