Installation of the TIM 3 / TIM 4 as CP in an S7-300
Introduction
This section explains the installation of the various TIM 3 and TIM 4 modules in an S7-300.
A SINAUT program is required on the CPU for data exchange between the TIM and the CPU
installed in the rack. This is created for the CPU with blocks from the SINAUT TD7 library
(TD7onCPU). When selecting one the CPUs listed below that can all be used in principle
with a TIM 3 / TIM 4, make sure that the work memory of the CPU is large enough to
accommodate the TD7onCPU program. The size of the program depends on the amount of
data to be transmitted, At least 20 Kbytes are required.
The TIM 3 / TIM 4 can be used in an S7-300 as the communications processor (CP) along
with one of the S7-300 CPUs listed below.
The following CPU lists also include older CPU types that can no longer be ordered as new
devices but that nevertheless may still be in use in the field. These are shown in
parentheses.
