Update
Offset(s)
Configures an offset time in seconds for the
update mapping. Used to stagger the update
transmissions so that each read message can be
timed to happen at it’s own time slot.
Response
Timeout(s)
This is the time in seconds to wait for a response
to the read request. For devices with high speed
radio, a value of 1 second is normally suitable.
Force Register
You can select another register to force the read
request to be transmitted, even if the update
timer has not expired. When the register is
written to a non-zero value, the transmission is
triggered. Once the message has been sent, this
register is automatically set back to zero.
otee:
N
Don’t use a Discrete input register (10001-10008)
as a force register. The Discrete input will not turn off,
and the mapping will continue to be forced while the
input is active.
Fail Register
You can select a physical digital output or a digital
register to signal if there was no response to the
read request. If no response was received for the
message within the configured response timeout,
then the fail signal will activate. If you are using
a physical Digital Output (register 1-8), the output
will turn On when the mapping fails to receive
the response message.
Sensitivity Blocks
allow you to configure how much an analog
signal needs to change to trigger a Change of State indication to
activate a Write Mapping. You can configure multiple blocks of
Analog signals. Each analog signal within the one block has the
same sensitivity.
Click on the “Sensitivity Blocks” link to access the configuration table.
Each line of the table defines one sensitivity block. Use the “Add
Entry”, “Insert Entry” and “Delete Entry” buttons to build your list of
blocks to configure. Edit the items as below:
First Register
The first Analog register in this sensitivity block.
Count
The number of Analog registers in this sensitivity
block.
Value
The sensitivity value. For 16-bit registers, this is
expressed in counts. For floating point registers
(range 38001 – 38040) this is expressed in the
inputs units (Volts, mA, or Hz depending on the
input type).
I/O Mapping Global Configuration
allows you to configure
advanced functions of the I/O mappings. The default values are
usually suitable, and will only need changing for unusual applications.
Tx Attempts for
Acknowledged
Messages
This is the number of times the device will
transmit a Read Mapping, or a Write Mapping
with the Ack Flag set, when it does not receive
a response to the message. If the message
is transmitted this number of times without a
response, then it will indicate as failed.
Tx Count for
Unacknowledged
messages
This is the number of times Write mappings
will be transmitted if they don’t have the
ACK flag set. You can configure to transmit
unacknowledged messages multiple times.
Acknowledge
Timeout
This is how long the device will wait for an
Acknowledgement when it is sending Write
mappings with the ACK flag set.
otee:
N
The Response timeout for Read mappings is set
in the individual read mapping configuration.
Default Back-To-Back gather scatter mapping
The 215U-2 comes pre-configured with a gather-scatter I/O mapping,
allowing you to send I/O data between the Base site and one
Remote site. This function is available in ProMesh mode, and maps
all of the I/O to appear at the remote site. You can enable this
mapping by checking the “Enable I/O Data” checkbox on the
Quick Start page. You can view and edit this mapping by selecting
“I/O Mappings >> Gather Scatter Mappings” from the Configuration
side menu.
This pre-configured mapping supports connection of 115S-12 and
115S-13 expansion modules to your Base and Remote sites to
increase the number of I/O. When you do this, you must configure
the 115S-12 with address 01 and the 115S-13 with address 02. You
set the address using the rotary switches on the bottom panel of
the 115S module. Refer to section “Adding expansion I/O modules”
on
page 22
for instructions on how to connect 115S modules.
otee:
N
You don’t need to connect the 115S modules. You can use only the
base and remote modules, or just connect one 115S-12 module at one end,
and one 115S-13 at the other end.
