PROBLEM TO BE SOLVED: To provide a programmable controller that increases the flexibility of connection of a support apparatus for accessing operation parameters for operation of a controlled apparatus, in a system including a programmable controller and an input/output device for data input/output to/from a controlled apparatus. SOLUTION: The programmable controller includes: a first request sending part for, when a request specifying an operation parameter is received from the support apparatus, converting the request and sending the converted request to the input/output device; a second request sending part for, when a first response indicating whether the converted request has been received normally is received from the input/output device, sending a read request instructing the input/output device to read out a processing result to the request; and a processing result sending part for, when a second response including the processing result information, which is a response to the read request, is received from the input/output device, converting the second response and sending it to the support apparatus.
