ISPSoft User Manual Example 3: There are three groups of output nodes. The first group begins with M100, the second group begins with M200, and the third group begins with M300. 32 output nodes at most form a group. After users add an output node rightward, they can create another group of output nodes. There is no limit on the number of output nodes which can be added rightward. Example 4: Some incorrect examples are listed below. 11-8 Incorrect example Description The data type of the input node must not be different from the data type of the output node. The data length of the output node must not be less than the data length of the input node.
The value of a symbol whose data type is REAL can not be sent to a D device. If the input node represents a symbol whose data type is REAL, the output node must represent a symbol whose data type is REAL. If the input node represents a symbol whose data type is LREAL, the output node must represent a symbol whose data type is LREAL. The data length of the input node representing a symbol whose data type is STRING and the data length of the output node representing a symbol whose data type is STRING must be the same. The value of a symbol whose data type is TIMER can not be sent to a symbol whose data type is DWORD, but can be sent to a symbol whose data type is WORD.
The value in a HC device can not be sent to a symbol whose data type is WORD, but can be sent to a symbol whose data type is DWORD. The multiple output nodes must conform to the rules listed above. The example is incorrect because the data length of the output node representing a symbol whose data type is INT is less than the data length of the input node.
