Introduction
This chapter describes specifications of the MicroSmart AS-Interface master module and applicable cables.
AS-Interface Master Module Type Number
The AS-Interface master module can connect a maximum of 62 digital I/O slaves. A maximum of seven analog I/O slaves
can also be connected to the AS-Interface master module (compliant with AS-Interface ver. 2.1 and analog slave profile
7.3).
The AS-Interface master module can be used with the 20-I/O relay output slim type CPU modules (FC4A-D20RK1 and
FC4A-D20RS1) and the 40-I/O slim type CPU modules (FC4A-D40K3 and FC4A-D40S3). Use a CPU module version of
201 or higher. When using
WindLDR , use ver. 4.21 or higher.
Module Name Type No.
AS-Interface Master Module FC4A-AS62M
Caution
• The AS-Interface master module cannot be used with the all-in-one type CPU modules and the
20-I/O transistor output slim type CPU modules.
• Only one AS-Interface master module can be connected to the slim type CPU module. If more
than one AS-Interface master module is connected, an error occurs and special data register
D8037 (quantity of expansion I/O modules) stores error code 40 (hex).
• Normally, a maximum of seven expansion I/O modules can be connected to the slim type CPU
module. But when the AS-Interface master module is connected, only a total of six expansion
modules can be connected, including the AS-Interface master module. Do not connect more than
six expansion modules due to the amount of heat generated. If more than six expansion modules,
including the AS-Interface master module, are connected, an error occurs and special data regis-
ter D8037 (quantity of expansion I/O modules) stores error code 20 (hex).
• The AS-Interface master module can connect a maximum of seven analog I/O slaves. When more
than seven analog I/O slaves are connected, the AS-Interface system will not operate correctly.
