精智TP2200触摸屏能通过MPI电缆和S7-200系列PLC通信么?如CPU224CN
我在TIA comfort V12里没找到S7-200的CPU啊。
佳答案
TIA comfort V12不支持S7-200,TP2200如果要和S7-200通讯必须走PROFIBUS,S7-200增么EM277模块。

程序已正常使用多年,出现问题后,上载来可以run。诊断如下:

佳答案
1、诊断信息:
BCD conversion error
Affected register: accumulator 1
Requested OB: Programming error OB (OB121)
OB not found, or disabled, or cannot be started in the in the current operating mode
Internal error, Incoming event
STOP due to: STOP caused by programming error (OB not loaded or not possible, or no FRB)
从上述诊断信息可看出是由于编程错误引起的STOP ,具体是由BCD码转换的错误。如果忽略这种错误可添加OB121,只需添加不需编程。
2、关于OB组织块:
CPU程序块里面需要添加一些对应的OB组织块,只需添加不需编程,当发生相应故障是CPU只报警,不停机。如:
OB81 电源故障
OB82 诊断中断
OB83 插入/拔出模块中断
OB85 优先级错误
OB86 扩展机架,DP主站系统或者分布式I/O故障
OB87 通讯故障
OB121编程错误
OB122 I/O访问错误
