Binary code
| Description | Read digital input(s) and assign a 16-bit TML variable with their value. When a single input is read, IN(n), the destination variable is set to 0 when the input n is 0 (low) and to a non-zero value when the input n is 1 (high). When multiple inputs are read, IN(n1, n2,…), each bit of the destination variable shows one input status: 0 – input is 0 (low), 1 – input is 1 (high). |
In TML the input lines are numbered from 0 to 15. Each product has a specific number of inputs, therefore only a part of the 15 input lines is used.
These instructions use a 9-bit short address for the destination variable. Bit 9 value X specifies the destination address range:
Execution Read input(s) and set their status in the corresponding bits from the destination.
