Domain Name System DNS MODBUS REGISTERS The x following the leading character represents a four digit address location in user data memory The leading character is generally implied by the function code and omitted from the address specifier for a given function The leading character also identifies the VO data type Register Functions Ethernet Digital I O DHCP refers to Dynamic Host Configuration Protocol and is a method used to assign temporary numeric IP addresses as required A DHCP server maintains a pool of shared IP addresses which are dynamically assigned and recycled When a DHCP device wants to use a TCP IP application it must request an IP address from the DHCP server The DHCP server will check the shared supply and if all addresses are in use the server will send a busy signal to the client which tells it to try again later Static IP addresses will ensure a connection every time but dynamic addresses do not DNS refers to the Domain Name System or Domain Name Server and refers to the system used to associate an alphanumeric character string with a numeric IP address The DNS is actually a distributed database of domain names and corresponding IP addresses These servers contain information on some segment of the domain name space and make this information available to clients called resolvers For example the DNS allows us to use Acromag com as an IP address rather than a complicated number

By convention the bits of the mask that correspond to the sub network address are all set to 1 s it would also work if the bits were set exactly as in the network address It s called a mask because it can be used to identify the unique subnet to which an IP address belongs to by performing a bitwise AND operation between the mask itself and the IP address with the result being the subnetwork address and the remaining bits the host or node address For our Example if we wish to further divide this network into 14 subnets then the first 4 bits of the host address will be required to identify the subnetwork 0110 then we would use 11111111 11111111 11111111 11110000 as our subnet mask This would effectively subdivide our Class C network into 14 subnetworks of up to 14 possible nodes each With respect to the default settings of this module Subnet Mask 255 255 255 0 11111111 11111111 11111111 00000000 IP Address 128 1 1 100 10000000 00000001 00000001 01 100100 Subnet Address 128 1 1 0 1000000 00000001 00000001 00000000 The subnetwork address of 128 1 1 0 has 254 possible unique node addresses we are using node 100 of 254 possible Nodes 0 10 and 255 are typically reserved for servers and may yield poor results if used Acromag Inc Tel 248 624 1541 Fax 248 624 9234 Email sales acromag com http Awww acromag com 2 2 BusWorks 981 982 983EN Module User s Manual Dynamic Host Configuration Protocol DHCP

67. underlying physical layer It is freely available and accessible to anyone easy to understand and widely supported by many manufacturers Modbus TCP IP uses TCP IP and Ethernet to carry the data of the Modbus message structure between devices That is Modbus TCP IP combines a physical network Ethernet with a networking standard TCP IP and a standard method of representing data Modbus A Modbus TCP IP message is simply a Modbus communication encapsulated in an Ethernet TCP IP wrapper In practice Modbus TCP embeds a Modbus data frame into a TCP frame sans the Modbus checksum as shown in the following diagram The Modbus checksum is not used as the standard ethernet TCP IP link layer checksum methods are instead used to guaranty data integrity TCP FRAME Transaction Identifier Protocol Identifier Length Field Modbus Frame a Modbus Checksum Not Included Sed MODBUS FRAME Note that the Modbus address field is referred to as the Unit Identifier in Modbus TCP Ina typical slave application the Unit ID is ignored and just echoed back in the response The operation of the 981 982 983EN industrial Ethernet modules is very similar to Acromag s 901 902 903MB ModBus modules The operation over Ethernet is essentially transparent to the Modbus register command structure If you are already familiar with Modbus or with Acromag Series 900MB modules then you are already familiar with the operation of the 981 982 983EN module
68. ximum query through the Modbus TCP interface is only 50 registers due to the maximum buffer size limitations of the TCP IP stack As such you can only request data from 50 registers at one time for commands that access multiple registers For example the Read Holding Registers command may only retrieve the contents of registers 40001 to 40051 in one read Register Mirroring Acromag Inc Tel 248 624 1541 Fax 248 624 9234 Email sales acromag com http www acromag com 2 4 BusWorks 981 982 983EN Module User s Manual Ethernet Digital I O Register Mirroring Data Types Oxxxx Coil Registers are mapped to 42xxx Holding Registers 1xxxx Input Status Registers are mapped to 41xxx Holding Registers 3xxxx Input Registers are mapped to 43xxx Holding Registers For 3xxxx Input Registers the format of the registers are identical and you only need to offset your address by 43000 For example if you want to read Input Register 1 through the Holding Registers you would use the Read Holding Registers function with an address of 43001 For the 1xxxx Input Status Registers the return data is reformatted to match the Holding Register format For example if you request the Input Status for 12 digital inputs instead of getting 2 bytes returned with the first 12 bits representing the 12 digital inputs you will get 12 separate words each set to either OOOOH OFF or FFFFH ON For the 0xxxx Coil Registers reads are handled i
