See table of error codes in the followingsection for more information.#255 ~ #252 - ReservedSymbols “R” refers to “able to read data by FROM instrcution”; “W” refers to “able to write data by TOinstrcution”.4.2 Explanations on CRCR#0: Model NameExplanations:1. Model code of DVPEN01-SL = H’4050.2. You can read the model code in the program to see if the I/O module exists.CR#1: Firmware VersionExplanations:The firmware version of DVPEN01-SL is displayed in hex, e.g. H’0100 indicates version V1.00.CR#2: Communication ModeExplanations:Bit No. Mode “0” “1”b0 Modbus TCP Disable Enableb1 Data exchange Disable Enable E-mail FunctionsCR#3 ~ 6: E-Mail Event 1 ~ 4 TriggerExplanations:When the CR is set as “1”, E-mail sending will be enabled. After the sending is completed, theCR will automatically be reset as “0”. Note: Please trigger by differential instructions.
