Function Key Description
[F1] Target Node Specifies the node number of processor that is receiving the message.
[F2] Remote LINK_ID 1 Specifies the LINK_ID of the remote network where the remote target processor resides.
[F3] Remote Bridge Node Address 2 Use when the remote target device is a SLC fixed, 5/01, 5/02, or any other nonĆinternet device. The value
must be 0 anytime your remote target device is a SLC 5/03, PLCĆ5, or other internet device. Valid range is
0 - 15 decimal.
[F4] Local Address Specifies the node address of the bridge residing on the local network that provides the link to the remote
target processor. Specifies DHĆ485 address.
[F5] File Address For a Read (Destination) this is the address in the initiating processor which is to receive data.
For a Write (Source) this is the address in the initiating processor that is to send data.
Valid file types are S, B, T, C, R, N, I, O, M0, M1.
[F6] Target Address For a Read (Destination) this is the address in the remote target processor that is to send data.
For a Write (Source) this is the address in the remote target processor that is to receive data.
Valid file types are S, B, T, C, R, N, I, O, M0, M1.
[F7] Message Length Defines the length of the message in elements. One word elements are limited to a maximum length of 1
-112. Three word elements are limited to a maximum length of 1 - 37.
[F8] Message Timeout Defines the length of the message timer in seconds. A timeout of 0 seconds means that there is no timer
and the message will wait forever for a reply. Valid range is 0 - 255 seconds.
[F10] Channel Identifies the physical channel used for the message communication. Available channels are (0, RS232) or
(1, DH485).
1 The Remote Bridge Node Address refers to the side of the remote bridge that is connected to the local bridge's remote side. This address must be
within the range of 1 Ć 15 decimal. When this value is between 1 and 15, the MSG instruction sends gateway" packets. Gateway packets need to
contain the Remote Bridge Node Address to function. The 1785ĆKA5 module only accepts gateway packets between 1 - 15. The 5/03 MSG instruction
contains a gateway packet anytime the Remote Bridge Node Address field is nonĆzero.
2 In the cases of MSG instructions to nonĆinternet devices and end devices residing directly on the DH+ link, the Remote LINK_ID is the DH+ LINK_ID.
In all other cases, the Remote LINK_ID is the DH485 LINK_ID.
