Problems solved by technology

[0011] Therefore, if there are multiple remote control input and output devices, and there are multiple deterioration diagnosis objects on each, it is necessary to set Figure 10 The program shown is described in the user program, which requires a lot of labor
In addition, by adding a program for such a login process, the amount of the overall user program also increases, and the cycle time of the PLC device side is slightly different from the cycle time of the system application. The reliability of the time difference data acquired in this state not necessarily guaranteed

Embodiment Construction

[0075] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. The structure of the PLC system of the present invention is shown in figure 1 .

[0076] As shown in the figure, the PLC system connects the PLC device 1 and a plurality of slave machines (remote control input and output devices) 2 in a communication manner through a field bus, and at the same time, on the communication path connecting the PLC device 1 and the slave machines 2, There is provided a passive monitor 4 which can passively monitor the communication data flowing between them.

[0077] In this example, the PLC device 1 includes a PLC 10 and a host unit 11 . like figure 2 As shown, the PLC device 10 includes: a CPU unit 101 for centrally controlling the PLC as a whole; / O units 102, 102....

[0078] like figure 2 As shown, the CPU unit 101 includes: a CPU 101a, which centrally controls the overall operation of the CPU; a program memor...

Abstract

PROBLEM TO BE SOLVED: To reduce labors when determining a threshold value, for example, in introduction of a programmable controller (PLC) system provided with an external equipment deterioration diagnostic mechanism and to secure the same operation in a system introduction and in a system operation, so as to collect a data of high reliability, as to the PLC system capable of referring directly to a deterioration diagnostic result by a ladder diagram, by notifying the deterioration diagnostic result of an external equipment carried out in a remote input and output device side, to a programmable controller unit side, via communication. SOLUTION: A rewritable tag for specifying a condition for issuing a transmission request command is set in every deterioration diagnosis, related to one external equipment deterioration diagnosis, in a device provided in a communication path between a programmable controller unit and a remote input and output device, and capable of monitoring passively a communication data flowing therebetween, and a command issuing means issues the transmission request command to the remote input and output device by referring to the tag. A desired data logging operation is properly carried out in the device, irrespective of a PLC. COPYRIGHT: (C)2006,JPO&NCIPI

Description

technical field [0001] The present invention relates to a programmable controller system, which can directly refer to the deterioration diagnosis result in a ladder diagram mode by notifying the deterioration diagnosis result of external equipment performed on the remote control input and output device side to the programmable controller device side through communication. Background technique [0002] The present applicant has proposed a programmable controller system (hereinafter referred to as PLC system) before this application, by notifying the programmable controller device side of the deterioration diagnosis result of the external equipment performed on the remote control input and output device side through communication, thereby It is possible to refer to the deterioration diagnosis result (for example, Patent Document 1). [0003] According to such a PLC system, as mentioned above, it is not necessary to incorporate message communication processing for taking in the...
