Abstract
A programmable controller sets access rules relating to permission or denial of access to a first data storage unit during execution of a second sequence program. In addition, a first sequence program is executed while accessing only the first data storage unit, whereas the second sequence program is executed while accessing the first data storage unit and a second data storage unit in accordance with the set access rules.
Claims4
A programmable controller configured to execute a plurality of sequence programs, comprising:
- a first data storage unit in which there are stored in association with each other state values, and identifiers of signal memories defined in a first sequence program;
- a second data storage unit in which there are stored in association with each other state values, and identifiers of signal memories defined in a second sequence program that differs from the first sequence program;
- a rule setting unit configured to set access rules relating to permission or denial of access to the first data storage unit during execution of the second sequence program;
- and
- a program executing unit configured to execute the first sequence program while accessing only the first data storage unit, and on the other hand, to execute the second sequence program while accessing the first data storage unit and the second data storage unit in accordance with the access rules set by the rule setting unit.
