AH500 Operation Manual 2.3.2 Configuring a Main Backplane A CPU module, a power supply module, and I/O modules are installed on a main backplane. Twelve I/O modules at most can be installed on a main backplane. 2.3.3 Configuring an Extension Backplane An extension backplane can be connected to a main backplane to increase the number of I/O modules. Eight I/O modules at most can be installed on an extension cable, and seven extension backplanes at most can be connected to a main backplane. 2.3.4 Maximum Extension Twelve I/O modules at most can be installed on a main backplane. (There are four types of main backplanes.
These four types are four-slot main backplanes, six-slot main backplanes, eight-slot main backplanes, and twelve-slot main backplanes.) Eight I/O modules at most can be installed on an extension backplane, and seven extension backplanes at most can be connected to a main backplane. (There are two types of extension backplanes. These two types are six-slot extension backplanes, and eight-slot extension backplanes.) Sixty-eight I/O modules at most can be installed on backplanes. Eight AH10EN-5A modules at most can be installed on a main backplane, and eight AH10DNET-5A modules at most can be installed on a main backplane. The other I/O modules can be installed on a main backplane unlimitedly.
Besides, digital input/output modules, analog input/output modules, temperature measurement modules, and AH10SCM-5A modules can be installed on an extension backplane. The other I/O modules can not be installed on an extension backplane. 2-9 POWER CPU I/O0 I/O1 I/O2 I/O3 I/O4 I/O5 I/O6 I/O7 POWER I/O0 I/O1 I/O2 I/O3 I/O4 I/O5 I/O6 I/O7 Extension Maximum Extension Description A main backplane is connected to extension backplanes One main backplane and seven extension backplanes (There are four types of main backplanes. These four types are four-slot main backplanes, six-slot main backplanes, eight-slot main backplanes, and twelve-slot main backplanes.
There are two types of extension backplanes. These two types are six-slot extension backplanes, and eight-slot extension backplanes.) Sixty-eight I/O modules at most can be installed on backplanes.
