The Rule for Assignment of Mapping Addresses for AS01DNET (RTU)
The start input and start output mapping addresses of AS01DNET (RTU) are assigned automatically by the master when
AS01DNET (RTU) is added to the master. The master assigns mapping addresses of AS01DNET (RTU) according to input
mapping address length and output mapping address length. Input mapping address length and output mapping address
length are determined by the configuration parameters of all modules connected to AS01DNET (RTU). The start addresses
of AS01DNET (RTU) will not be assigned until AS01DNET (RTU) is added to the master and they are related to the order
of adding slaves to the master.
When there are two slaves of AH10DNET and AS01DNET (RTU), the input size and output size of AH10DNET are both 4
bytes and the input size and output size of AS01DNET (RTU) are both 4 bytes. If AS01DNET (RTU) is added to the master
before AH10DNET is added to the master, then the input mapping addresses and output mapping addresses of AS01DNET
(RTU) are respectively D26005~D26006 and D26105~D26106 as below. D26005 and D26105 are respectively the start
input mapping address and start output mapping address, i.e. status word and control word of AS01DNET (RTU). The
registers after start input mapping address and start output mapping address are for mapping the configuration parameters
of I/O modules.
