12-1 12 Chapter 12: Errors and Countermeasures The operating condition of the JW-21MN can be monitored using its indication lamps, flags, and the system memory of a PC. 12-1 Indication lamps LED "1" to "80" indicate error codes when an error occurs.
12-2 12 12-2 Flag Flag area is 24 bytes from the "flag top address" set in the master station/slave station parameters. [1] Flag table [ In case of flag top address is ｺ 0740 (initial value) ] - Even a slave station can monitor 24 bytes of flag.
12-3 12 [2] In the case of a master station (1) Communication monitor flag This flag is used to monitor the communication condition with other stations. Non-connected station keeps this flag as "OFF." The master station periodically executes communication recovery operation with the communication error slave station.
12-4 12 [3] In the case of slave station 01 to 77 (8) (1) Communication monitor flag This flag is used to monitor the communication condition with other stations.
12-5 12 [4] Monitor operation condition by each station PC By creating a program having the flags shown below in each station's PC, the JW-21MN can monitor the operation condition of each station’s PC.
12-6 12 12-3 Storage of error code When an error occurs in the JW-21MN, it stores the occurred error’s code to system memory #160, #170 and error history storage register of each station's PC. - In some cases, error code 23 (H) or 2A (H) is stored when inputting power.
12-7 12 (1) System memory #170 to 177 (option module error code) The error code stored in the system memory #170 is shifted to #170 to #177 one after the other as new errors occur. Thus, the system memory can store up to 8 errors. When the PC is operating by RAM, these error codes do not disappear even after turning OFF the power.
12-8 12 (4) Error history When the JW-21MN has errors, it stores them in an error history register. The storage area is specified using the module No. switch setting value. The storage area for the error history (128 bytes) is divided into 8 sections (16 bytes each).
