Time required for a reset of a PCM module (model 331 CPU only) to be completed can be up to a minute for long scan times. The approximate time required in milli- seconds can be computed by multiplying 300 times the scan time in milliseconds. UVEPROM Change 2. The User Program, configuration, and status tables will automatically be cleared when the CPU 331 PROM (U19) is changed. Rack Size Mismatch 3. Configuring a model 331 rack size which is different from the actual rack size will produce a ”Non-fatal hardware failure” fault in the PLC fault table. This is only a diagnostic fault, and will not inhibit the PLC from going to RUN mode. Although RUN mode is allowed, problems may occur during RUN mode due to the mismatch. 1. Off Delay (OFDTR) Function 14 The off-delay timer (OFDTR) increments while power flow is off, and resets to zero, when power flow is on. Time may be counted in tenths of seconds (the default selec- tion), or hundredths of seconds. The range is 0 to +32767 time units. The state of this timer is retentive on power failure; no automatic initialization occurs at power-up. When the OFDTR first receives power flow, it passes power to the right and clears the current value (CV) located in the operating registers of the timer. The output remains on as long as the function receives power flow. If the function stops receiving power flow from the left, it continues to pass power to the right and the timer starts accumulating time in CV. Each time the function is invoked with the enabling logic set OFF, the cur- rent value is updated to reflect the time since the timer was turned off. When the cur- rent value (CV) is equal to or greater than the preset value (PV), the function stops pass- ing power flow to the right. When the function receives power flow again, the current value resets to zero and the output is enabled again. Operational Notes: New Features: 4 Important Product Information GFK-0702G ENABLE Q A BCDE FGH A = ENABLE and Q both go high; timer is reset (CV = 0). B = ENABLE goes low; timer start accumulating time. C = CV reaches PV; Q goes low, and timer sops accumulating time. D = ENABLE goes high; timer is reset (CV = 0). E = ENABLE goes low; timer starts accumulating time. F = ENABLE goes high; timeris reset (CV = 0). G = ENABLE goes low; timer begins accumulating time. H = CV reaches PV; Q goes low, and timer stops accumulating time.
