SR4 SR4 is refreshed when there is a grammar check error SR5~SR6 The register is refreshed when the program is downloaded to the PLC, or when the PLC is suppied with power and starts to run for the first time. SR8 SR8 is refreshed when there is a watchdog timer error. SR40~SR161 The register is refreshed when an error occurs. SR201~SR216 Users set the value and clear it. SR220~SR226 The register is refreshed every scan cycle.
