}Configuration error
}ST communication error
}Bus termination error
}Temperature error
4.2.4 Reaction times
Information on the reaction times of the inputs/outputs can be found in the "PSSuniversal"
System Description and the System Description "Automation system PSS 4000".
4.3 Configuration
It is not necessary to configure ST inputs/outputs in the PSSuniversal Configurator on the
PSSWIN-PRO system software, but ST modules can be selected and displayed.
The ST process image can be optimised by combining adjacent bits of the same type into
bytes.
Further information on configuration is available in the PSSuniversal Configurator's online
help.

5.2 Install compact module
Prerequisite:
}The head module must be installed.
}If the head module does not have an integrated power supply, a supply voltage module
must be installed to the right of the head module.
}A base module with screw terminals may not be installed to the left of the compact
module.
Please note:
}All contacts should be protected from contamination.
}The mechanics of the compact modules are designed for 50 plug in/out cycles.
Procedure:
}Slot the groove on the compact module on to the mounting rail from below [1].
}Push the compact module back as far as it will go [2].
}Make sure that the locking mechanism [3] is pushed downwards, connecting the mod-
ule firmly to the mounting rail.
}On the mounting rail, slide the compact module to the left.
NOTICE
Potential contact damage due to twisting!
The contacts for the Module Supply and Periphery Supply can be bent by
twisting the compact modules on the mounting rail.
– On the mounting rail, carefully slide the compact module to the left, in
parallel to the adjoining module, until you hear the lateral mounting
hooks on the adjacent module lock into position [4].
