SIL3 application, PM865 with SM811
recently i came across a piece of coding in a SIL3 application where a particular bit ( bool) is made to on and off at the same time . on checking it is found that the bit is made off during first download ( may be initialising) and then there is another code on other location ( which is a part of continuous scanning) which make it On or Off dependent upon condition. Now my question is that during the first download how the controller will behave because it will scan both the codes in the first download it self .
