Hi Is it necessary to use channel driver like Pcs7DiIn and Pcs7DoOu for all the input and outputs? |

Hi manmeet, No it is not necessary, but using channel drivers enables diagnostic capability. When errors occur on the hardware, this is signalled through the channel drivers. You can connect the channel drivers to a technology block like a valve. An error or problem can be made visible on the technology block (connecting the Bad signal of the driver block to CSF of the valve). The channel drivers also make sure the correct mode is set like 4-20mA or 0-10V according to the hardware settings of the I/O and scaled automatically -> 4-20mA =0-100bar for example. If not using drivers, you have to make the conversion yourself. It makes no sense to do this though since the drivers are available to you by using the AP library. |
