6-2. How to Read Special Internal Relays(R) & Special Data Registers(DT)
76
3. Table of Special Data Registers(DT)
The special data registers are used for special purposes in the Programmable Controller.
Data cannot be transferred to the special data registers(except for DT9060 to DT9122).
DT9017/DT9018(Data Transfer instructions ; Error program address)
DT9039(Data Transfer instructions ; Error code)
DT9140 to DT9159(P/W PC Link status)
Address Description
DT9017 The error program address is stored, when R9007 turns ON.
DT9018 The error program address is stored, when R9008 turns ON.
Address Description
DT9039 The following error code is stored, when R9031 turns ON.
71(hexadecimal) : Response signal meaning that a Data Transfer operation cannot be received.
72(hexadecimal) : The Data Transfer buffer is full.
73(hexadecimal) : Response message cannot be received.
When one of the above mentioned errors occurs, check the time-out value in the system register
number 32. The time out value can be set in the range of 10ms to 81.9s(default = 2s).
