    Safety FBs are the manufacturer offer function blocks that received the certification of ISO13849-1:2015 PLe, IEC62061:2012 SIL3, and IEC61508:2010 SIL3. The safety FBs can be used with the MELSEC iQ-R series safety CPUs. Improving the productivity and the maintainability of a safety program The major functions used in programming safety applications are provided as the safety FB library.

Name Function Description Reference Two-hand switch Type  M+SF_2HAND2_R_01A This FB provides the two-hand control functionality. Page 15 M+SF_2HAND2_R Two-hand switch Type  M+SF_2HAND3_R_01A This FB provides the two-hand control functionality (Fixed Page 19 M+SF_2HAND3_R specified time difference is 500ms).
  • Page 11: Common Specifications

    Common Specifications This section describes the common specifications to each safety FB. The following table lists the general input/output specifications of the safety FBs. Variables other than i_bS_In and o_bS_Out are all used under the same names, data types, default values, specifications, and functions for the safety FB use. For details on each name, data type, default value, specification, and function of the safety input-output variables other than those described in the figure below, see the description of individual safety FB.
  • Page 12 ■ Output labels Name Data type Default value Description and variable value o_bReady Status of whether the safety FB is activated or not. OFF: The safety FB is not activated. ON: The safety FB is activated. For details on the function, see the following. Page 11 Whether safety FBs are active or not ...
  • Page 13: General Functions

    General Functions Whether safety FBs are active or not Input signal, i_bActivate, sets whether to activate a safety FB or not. In addition, whether the safety FB is active or not can be checked with output signal, o_bReady. If i_bActivate is OFF, all values of the output signals are set to the default values. Inputting the signal of the safety refresh communication status for CC-Link IE Field Network inactivates the safety FB when an error occurs in the safety station and then prevents unnecessary signals from outputting.
  • Page 14: Generic State Diagram

    Generic State Diagram The safety FB state transitions according to the state diagram described in the safety FB specifications. However, a program operation is suspended while the operation status of the CPU module is in STOP or PAUSE. Consequently, the state transition does not occur.
