DINT (32-bit integers) - Manual - SIMATIC S7 Connector - Industrial Edge - Industrial Edge App

An operand of data type DINT (Double INT) has a length of 32 bits and consists of two components: a sign and a numerical value in the two's complement. The signal states of bits 0 to 30 represent the number value. The signal state of bit 31 represents the sign. The sign may assume 0 for the positive, or 1 for the negative signal state.

An operand of data type DINT occupies four BYTE in the memory.

The following table shows the properties of data type DINT:
