xCP MODBUS SLAVE and MASTER for S7-300/-400 PLCs
CP-independent, plain Step-7 code MODBUS drivers
Runmode xCP stands for “cross Communication Processors”, a software driver that is not tightly wrapped around any specific S7 CP. It thus allows a large degree of freedom in selecting for your project the best serial Communication Processor (CP) at the lowest price.
xCP MODBUS is a set of S7 blocks coming in two versions: Modbus RTU Master and Modbus RTU Slave.
Your CP choice may include rack mounted or networked CPs, either by Siemens or by other manufactures (e.g. Vipa, Wago, Helmholz, etc).
Tunnelling Modbus RTU, go Ethernet to serial!
xCP drivers can also be used for Modbus tunnelling via Ethernet. This means that by using an Ethernet connection you can access non-Modbus/TCP serial compliant devices . If your S7 PLC is equipped with an Ethernet port, simply use an Ethernet-to-serial converter to act either as Modbus RTU Master or Slave.

No ties
The driver’s S7 blocks are not protected and fully commented. No hidden code, everything is before your eyes
No multiple license hassles
As long as you sell your PLC programs, the license grants you to include an unlimited number of copies of the driver. So buy once and reuse as many times you need. The only bound is the commitment to not resale nor distribute freely the driver.
Start saving money NOW!
- Get rid of high cost CP341 / CP441 and their very expensive Modbus dongles.
- Get rid of license cost you must pay at each installation.
- Buy a single license of Runmode xCP MODBUS and install as many copies you need.
Check yourself how much you can save
The following example shows an entry level solution by Siemens (CP341 and its loadable driver) and an alternate solution using a cheaper CP340 and RUNMODE driver.
Shipping and billing
The program, registration code and invoice will be sent via e-mail upon payment.
